And it's not forgotten. I will have a look how to move the cpu-specific part
into powerpc/oea/cpu_subr.c in the following days (weekend?). Suggestions
for the cleanest implementation are still welcome. ;)

That's my only card, unfortunately. I will ask if somebody else got another
card and report back.

I checked the stride. It is calculated as 1280, which should be normal for a
width of 1280 pixels and a depth of 8 bits.

But maybe the depth is the problem? I found this comment in
radeonfb_init_screen():
        /* XXX: 32 bpp only */

It worked with 5.0.2, but with current it fails again. First it didn't want
to accept the xorg.conf, which I created with 5.0.2. Then, after I deleted
all lines which are obsolete, I got:

(++) Using config file: "/etc/X11/xorg.conf"
(EE) No devices detected.
Fatal server error:
no screens found

Also running configure no longer works and crashes:

# X -configure

X.Org X Server 1.6.5
[...]
(++) Using config file: "/root/xorg.conf.new"
Using rom_base = 0xb0020000 (pci_rom=1)
Using rom_base = 0xb0020000 (pci_rom=1)
Fatal server error:
Caught signal 10.  Server aborting

Maybe I missed something while updating my userland from 5.0.2 to current?
