No.

| If your kernel binary is simillar to mine, it looks like that 
| fbops->fb_imageblit was NULL. It should not happen, as matroxfb's 
| fb_imageblit should point either to no_imageblit (which currenlty does 
| nothing, but it should complain loudly) or to cfb_imageblit (which 
| paints character) or matroxfb_imageblit (which should paint character too).
| 
| But from call trace it looks like that some printk() error got
| triggered on your config. Can you try booting with serial console? 
| Do you see penguins on the screen, or not? 

No penguins on screen.
I don't see any problems logged.  I did boot with serial console.
It's attached.

| Or remove body from drivers/video/console/fbcon.c:check_vc() - it should
| is not triggered on Linus kernels, but maybe -mm1 moved something around.
| It looks like that it is time to download -mm1 :-(

Actually this is just 2.5.67 + mga-2.5.66-bk12 with and without my
earlier-keyboard-init.patch...
