Hi,

The plain 2.1.63 didn't really work for me; i got just one of these:

<c2800fc8/c2800ff8>
<handler c01098b4... ... done>

but i could still swap virtual consoles, and get shift-scroll info.

Linus' clean-up patch to pl63 works a lot better. Running my while
do ./peteum done produces:

llegal intstruction (core dumped)
jippie
llegal intstruction (core dumped)
jippie
...

no lock-ups, and it actually dumps core.

produces a kernel that just:

Uncompressing Linux...done
Now booting the kernel
<nothing more>

perhaps someone knows what options are better left unselected:
