Successfully applied patch to my tree (Debian's 2.6.18-something), but I
have a build problem somewhere I haven't been able to finger out.

Going to DL a Vanilla 2.6.19 kernel and apply it and do it the
non-Debian way to see if it does work. Maybe if it does work, I can get
the patch applied to Debian's tree for Etch...

More tomorrow. (or maybe a bit later than that)
