Well, i've tried test program on 2.6.22-rc4 with your PCI patch
(cf58de958f939587637ea74cdc3382bc140a936b) and on plain 2.6.22-rc5.
Here's the results.
2.6.22-rc4 + PCI patch:
x0:0x8e100020
x8:0x00000000
2.6.22-rc5:
x0:0x8e100080
x8:0x00000006
Seems that your patch was not the only related change between -rc4 and -rc5.
Anyway, X still doesn't work with -rc5 so probably problem is somewhere
else. I sent you privately strace logs for X with 2.6.22-rc5.
