Hm, xfs_repair does not ask any questions.

In the logs on my main machine, it showed the following when it
attempted to mount the two filesystems (root and boot, /dev/hde4 and
/dev/hde1 respectively).

Ok, so XVM has found something wrong at this point. Any chance the box had a power failure? Write caches on ide drives can wreak havoc with journaling filesystems... i.e. what happened between "the filesystem was working" and "i remounted the filesystem and got this"

As far as bad disk/memory, I have tested both systems with memtest86 and the result was 0 errors, as far as the disks go, I have not experienced any problems with either of them until I moved to 2.6.9/2.6.10-rc{1,2}.
