Yes, this worked, thanks! I'll describe my build process, for the
benefit of others. In my next message, I'll describe the next stage
of uncertainty....
Also, below, is a memory limitation I encountered.
1. mkdir xen-new ; cd xen-new
2. bk clone bk://xen.bkbits.net/xeno-unstable.bk
3. ./xeno-unstable.bk/tools/misc/xen-clone bk://xen.bkbits.net/xeno-unstable.bk
I noted that ReiserFS was not in this kernel, so:
4. cd xeno-clone/xenolinux-2.4.22
5. edited .config to add ReiserFS support (could "make menuconfig")
6. make dep; make bzImage
7. cp arch/xeno/boot/image.gz ../install/boot/xenolinux.gz
Then, copied the images to /boot:
8. cd ../install/boot
9. (as root) cp image.gz /boot/ ; cp xenolinux.gz /boot/
My (working) /boot/grub/menu.lst is:
title xen
root (hd0,0)
kernel /image.gz dom0_mem=768000 ser_baud=115200 noht
module /xenolinux.gz root=/dev/sda2 ro console=xencons0 DOMID=0
This works fine with a 768MB memory limit. However, when
I tried it with "dom0_mem=1024000" I got an immediate reboot
after the kernel loaded. As mentioned earlier, this machine
has 2GB of physical RAM, which seems to be mapped contiguously.
After re-adding items to my fstab, "df -k" is:

Thanks again for this help! On to virtual domains, next...
