FWIW, I got my neo2 X2 working as well - details:

For me it wasn't drivers / bios / firmware. It was purely the Server 2003 Resource Kit filter installation and restoring my DmaTurbo registry setting to 1.
I can run it sucessfully under SP1 and SP2 XP partitions and it seems happy with either. (SP1 = music partition, SP2 = Web surfing and light music work)
Note that I had a perfectly running single core system XP SP1 that I only upgraded the cpu to dual core on - so YMMV since you may be dealing with other system issues that aren't dual core related. I didn't do a complete windows reinstall for the upgrade - just changed the appropriate drivers and made sure I was up-to-date on everything. So just letting you all know dreams can come true!
