*** 2.6.26-rc1 gets as far as the line above, then hangs

It's possible your machine does boot up all the way.
The video driver simply isn't registerring for whatever
reason.

Can you ping the box if you wait a minute or two after the
messages stop?

The only patch to the aty driver since 2.6.25 is the
following, below, which you can try reverting.

Another thing you can do is edit arch/sparc64/kernel/setup.c
and in the prom_early_console struct initializer, remove the
"CON_BOOT" bit from the .flags setting. That will keep the
PROM console enabled even when another console wants to
register. We'll get more messages that way.

I've got the same issue on a Sun Blade 1000, doing the CON_BOOT thing this is what i get, obviously it just hangs and i can't return to OBP.
