Bug free X61t Win7x64: BIOS? Drivers? TV System Update Apps?

Ive been having tons of GRIEF over last 2 weeks,

XP & Windows 7 both: Possible Hardware / Driver / BIOS Issues as WinXP & 7 were Freezing at bootup
SMBIOS Standards test Fails X61T
T61p - PCI Memory Controller
Reflashed the factory BIOS and OS boot, but now XP BSOD issues.

XP Issues:
WHY Frequent BSOD: INVALID_WORK_QUEUE_ITEM 0x96 ntoskrnl.exe - Even when idling 5/10 minutes.
Has kind of disappeared or decreased since I disabled the Hardware Wireless switch or so it seems for now.
BSOD Fix on German Thinkpad.de forum Please Help Understand

Windows 7 Concerns and some Issues:
X61T, Windows 7 x64: Drivers and APS problems
x61 tablet: Scrolling in Portrait Tablet mode?
Trimming the fat from thinkpad Windows 7 installs.

Solution Direction: Questions & Concerns
So Ive decided to move off from my WinXP to Windows 7 x64.

My concern is given the varying ways that this can be done, I do not want to have a system that starts wierding out on me due to some DRIVER and other issues.

I'd appreciate if you could share from your experiences with
Win7 x64 (maybe 32 as well) run on the X61 Tablet or close cousins X61(s).
Please do post your experiences with some details of the following parameters.

TV System Update v/s Default Microsoft ones and for which devices?
Device: X61T, X61/s
Which Windows 7 (64 vs 32),
BIOS (Version No, Factory / Zender / Middleton),
DEVICE DRIVERS (Default Windows 7/ Vista 32 or 64/ Intel or Lenovo TV System Update) and
Apps (Thinkvantage/Lenovo / Intel are you using?

Specific Devices:
- Video Driver & Control Apps? Default MS or from Intel or via Thinkvantage?
- For Storage, are you using Intel or Lenovo drivers or default Windows 7? Varying Experiences with them?
- Tablet buttons drivers? In Tablet Mode Scrolling working in Apps and especially MS One Note?
- Fingerprint Scanner? via TV System Update? - Working fine? (I know its not super secure, but I like its convenience so I can swipe a finger instead of type whole password, while I am eating and reading off the x61t)

- Wireless Control
- Have you had any issues with enabling / disabling the Wireless / Bluetooth via the Fn F5?
- Can this only be installed if we install TV Access Connections?
- Is the Wireless Driver working fine?
- Were there any issues with Access Connections? I have liked using it over Windows default in XP.

-Bluetooth Stack & Functionality
- Can you/ have you installed a more complete Bluetooth Stack to replace Win7 default stack? From TV System Update or downloaded from Lenovo Site or 3rd party Stack?

General
- Is there any scenario or drivers where the Vista Drivers are working better for you?
- ALSO at certain times I have found OLDER VERSIONS of ThinkVantage Apps better. e.g. Access Connections that was originally there on my T61 and X61T on XP was much better before their updad versions started become slow, inconvenient and bloated.

... More thoughts and questions coming up.. Ill post this for now.
