Whoops, too many dots in kernel-source-2.6.8-2.6.8. That should be:
<http://svn.debian.org/viewcvs/kernel/trunk/kernel/source/kernel-source-2.6.8-2.6.8/debian/patches/x86-i486_emu.dpatch>

The thread can be read here:
<http://thread.gmane.org/gmane.linux.kernel/205839>. People find various
problems w/ the patch. Alan Cox proposes an interesting alternative
(trapping SIGILLs and emulating the necessary instructions in userspace),
but I haven't seen any implementations of it.

I believe the 20meg version *is* the lowmem install target. The standard
one requires something like 32 megs, last I heard.
