It's nice to know I am getting closer.  Thanks for all your help!

I don't see any evidence that GRUB is passing a mem= option to the kernel.
Maybe Debian's grub has it patched out.  It's not in /proc/cmdline or the
dmesg output.  Nevertheless,  I tried --no-mem-option as you suggested,
and it made no difference.

Here we have the D845GLLYL, 2.6.4, the pcmcia-10 patches, and the
pcmcia-ti-routing-9 patch.

This machine does have 1G of memory, with himem enabled.
