SubjectRe: Alpha SCSI error on 2.4.0-test11

Compile again with the following patches (these are against 2.4.0-test12,
but those in arch/alpha/kernel/core_cia.c should work against test10/11
as well).

Something got lost between 2.2 and 2.4, but it's most likely that
MIATA (because it has 6 DIMM slots) is one of the few CIA and PYXIS
machines that could actually get over 1GB of memory; that's why we
haven't seen this before...
