Yes I do the analysis, actually only one method is used
(PCI_mapBIOSImage), but there are two other methods related to video
card. Booth in file drivers/bios_emulator/atibios.c (PCI_mapBIOSImage,
PCI_unmapBIOSImage). Nothing calls they but I think they can be
preserved too.

But there are a lots of other code which can be removed. For example
BE_mapRealPointer() from drivers/bios_emulator/biosemu.c or
BE_getVESABuf() from same file. So my question is: It is safe remove
dead code or somebody can use it for debugging purposes ? I've got
same problem with another driver so this is general question.

Best regards,
Viktor Krivak
