I see.
How about the following patch?
As an illustration this gives following output for some cards:

  radeonfb (0000:01:05.0): ATI Radeon 5975 "Yu"
  radeonfb (0000:02:00.0): ATI Radeon 5b60 "[`"
  radeonfb (0000:02:00.0): ATI Radeon 5960 "Y`"


Regards,

Andreas

Additionally provide PCI device id in character format if possible.
(The printable characters were commonly used to identify the cards.)
