btw I had it on 2.6.0-test4 and on -bk2 and on -mm1

Not sure what that is.

This error started with -mm2:

What's the taint?

Works OK here.  Could you please do `strace lilo', see what the offending
ioctl args are?

setfont sets font only for the current tty and not for all ttys like 2.4 do.

hm, I wonder who to blame that on.
