lspci -vxx and dmesg attached. I have disabled all under IDE menu, I'm running 
only on libata now. With the patch from Mark Lord I can see the cdrom drive, 
but as /dev/sdb, not /dev/sr0, and I have some messages like

ATA: abnormal status 0x58 on port 0x177

(see dmesg). Haven't tested much, but apart from the speed issue it seems 
stable. hdparm -Tt says:

/dev/sda:
 Timing cached reads:   1124 MB in  2.00 seconds = 561.57 MB/sec
 Timing buffered disk reads:    8 MB in  3.76 seconds =   2.13 MB/sec
