I assume you use the extended patch version from this page
(http://bugme.osdl.org/attachment.cgi?id=4576&action=view)
1.) Is our tp model equiped with a radeon mobility device?
2.) Is it added into the whitelist-patch? so in this way? I do not think
so, because I cannot find a R50 Model inthere.

  .ident = "IBM ThinkPad R40 (2722-B3G)",
+               .matches = {
+                       DMI_MATCH(DMI_SYS_VENDOR, "IBM"),
+                       DMI_MATCH(DMI_PRODUCT_NAME, "2722B3G"),
+               },

replace with your data, if 1 is correct...
3.) Have you enabled radeonfb in you kernel config? disabled vesa?
CONFIG_FB_RADEON=y
CONFIG_FB_RADEON_I2C=y
# CONFIG_FB_RADEON_DEBUG is not set

4.)choose sth. like this in lilo/grub conf:
append="video=radeonfb:1024x768-16@60 acpi=on noresume2 acpi_sleep=s3_bios"

important are the "radeonfb" and acpi_sleep=s3_bios to get your screen
back, after resume, but that`s another issue.
