How to enable HIGHMEM in sid?

[Charlie Zender <zender@uci.edu>]

Hi,

I am running Debian sid on a Dell laptop with 1 GB RAM.
dmsg tells me that this warning occurs during the boot process:

"Warning only 896MB will be used.
Use a HIGHMEM enabled kernel.
896MB LOWMEM available."

Does this mean what it sounds like? i.e., that I'm only going to
be able to access 900 MB RAM unless I install a kernel with HIGHMEM
enabled? If so, are there .debs of kernels with HIGHMEM enabled,
or should I build from scratch? Or is there a configuration/boot
switch that does this?

Thanks,
Charlie
