It means IBM ramdac..the card is still IMS TT..weather with IBM or TVP
ramdac..if you have TVP try patch below, if not please send me as much info of
your car as possible.
..against 2.4.20(afaict); just a dirty patch but it works for me:

Yes, without it "detects" IBM ramdac according to PCI ID's, but i have
TVP 3030 (Texas Instruments) ramdac on the bord..looks like someone
didn't bother to change the PCI ID of the card..
