Move BF2 cache folder

As a followup for my last post: http://www.opentechsupport.net/forum...443#post278443 comes this question.

Let me explain my drive/system setup.

C: 250 GB SATA disk, with my games and windows
D: 200 GB 7200rpm ATA disk for storage, movies, mp3 etc

for reference: I have 1 GB dualchannel RAM 400mhz

I moved my 'my documents' folder also to D: (so I can easily format C: when nessecary).

Now battlefield 2 generates the shader cache in my documents, which is on a slower disk, so I was thinking about if moving the cache, if possible (somewhere in bf2 config change a path?) to the C: disk would improve performance?

Thanks in advance!
