question on ipp linux version on intel pca

Dear Sir,
I'm writing some codefor a board based on intel pxa255,whosesystem is linux, kernel-2.4.19. Unfortunately I met some fatal problem when using intel ipp and I'll be appreciate if you can answer me some quests.
1. I want to confirm whether only the IPPv3 is properly for my system. I learnt from this forum that IPPv4 with mmx support might not run properly on PXA255 linux system. i'z t?
2. I've choose IPPv3 to go ahead with my work. However, iz't support the MPEG4 decoder? And is there a manual or handbook for IPP version 3 rather than the version 4? If no, I wonder if there is much diff between v3 and v4 since I got IPPMANUL for v4.
3. Does IPPv3 support MPEG4 decode process? Also, is there a sample for v3 rather than v4?

Thks.
Luke
