Yes this is the way to go, for example the entry for my R40 2722-B3G 
looks like that:

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

just edit this entry to fit to your values.

If you go into S3 mode you should see sth. like that:
radeonfb (0000:01:00.0): suspending to state: 3...
radeonfb: switching to D2 state...
radeonfb (0000:01:00.0): resuming from state: 3...
radeonfb: switching to D0 state...

D2 state is the important thing.

I did compile radeonfb (new version) directly into the kernel and my 
append lilo conf for 2.6.11-rc2 looks like that:
         append="video=radeonfb:1024x768-16@60 apm=off acpi=on 
pci=routeirq resume2=swap:/dev/hda5 acpi_sleep=s3_bios"

good luck
Peter
