Such list already exists. gfx_chip_name = pdi->driver_data in hw.c (and 
only there) so what is needed is the list viafb_pci_table in viafbdev.c 
(relatively at the end) of all chips:
UNICHROME_CLE266
UNICHROME_PM800
UNICHROME_K400
UNICHROME_K800
UNICHROME_CN700
UNICHROME_K8M890
UNICHROME_CX700
UNICHROME_P4M900
UNICHROME_CN750
UNICHROME_VX800
UNICHROME_VX855

Would appreciate it if you could use this info.


Thanks,
