Is Intel Q9200 processor compatible with Precision M4400?

Hi, I'm looking for a quad core chip for my machine and since qx9300 processor is still way overpriced and it can't be overclocked due to BIOS limitations, i think the 9200 model is better deal. But this processor seems still rare to find, there are very few ones on ebay . Also there are compatibility problems with Dell M4400 according to sellers. For example look at this:

Could anyone who tried this processor on Precision M4400 confirm this? Are there steppings that don't pose this problem?.
Thanks in advance.

 

The Q9200s for sale are all engineering samples - the production model with S-spec SLB5H hasn't come out yet - which explains why they are 'rare', not to mention the compatibility issue. Right now your only choices for quad-core are the Q9000, Q9100 and QX9300. My genuine QX9300 was only $500 from eBay... looks like I got a good price!
