Slightly different then. I don't know of anyone regularly testing 2.5.x
on 4MB machines, which might need a bit of help on this front if more
memory than they have is flushed down the toilet at boot.
I've got a collection of ancient toasters but the ports aren't booting,
and for reasons far deeper than this. 4MB bochs/x86 laptop? No time. =(
Cheers,
