Thanks Brice,
Creating the source RPM:
rpm -bs some-spec-file
You spurred me into looking to see if cheap RAM was to be had for my
Powerbook Lombard, now that I've got drive space, but it doesn't look to
be so cheap in the couple of places I looked ;^)
I'll be sure to enable high memory in the next kernel I patch up for PPC.
Thx,
Stew Benedict
