    Thank you. I tried that, but they don't seem to have included the 
pm2fb driver. And I've searched the net, and haven't found anyone else 
using it on a 2.6 kernel either.

    I've come to the conclusion that the permedia2 FB driver is broken 
in 2.6(.8?), at least when it comes to the Raptor GFX board in an E250. 
The system will boot, but nothing gets displayed on the screen (the 
monitor doesn't see any signal at this point). I did get the thing to 
boot with the PROM console, and can log in that way (after I figured out 
how to disable console keymaps). But the glint X driver doesn't work 
under these conditions (it segfaults), and neither does the X 
framebuffer driver (it segfaults too). Both work under a 2.4 kernel 
(although glint has real problems).

    So I'm going back to 2.4 kernels for now. At least they work.

    One thing I found while working on this is that I had to enable 
SERIAL_SUNSU and SERIAL_SUNSU_CONSOLE before I got a functioning 
keyboard and mouse (never noticed till I got the prom console going). 
Surprisingly, the default config under arch/sparc64 didn't see fit to 
include them.
