I have a 750CXe in my Pegasos2. Maybe I will look into it some time later,
when you don't want to do it.

Yes, and it's set to 1280, which is also the stride readonfb is using.

That's for ofb(4), but the mmap problem disappeared indeed when using
WSFB_FAKE_VGA_FB. ;)

It's not in any config file, BTW. Maybe we should change that?

Unfortunately it didn't have any influence on the fatal server error:
[...]
(II) RADEON(0): initializing int10
(II) RADEON(0): No legacy BIOS found -- trying PCI
Fatal server error:
Caught signal 10.  Server aborting


Here is the ktrace dump between "initializing int10" and the fatal server
error:
