IF someone hasn't already pointed it out, the kernel takes the memory and 
bridge map from the BIOS unles you override it.  Dell was infamous for bad 
bridge mapping on the BIOS for at least a couple of their inspiron notebooks 
(try to take an i4000 over 256M and see), but it may not be the only culprit 
on the block.  Kernel 2.2 actually worked on the i4000 up to 512M but then 
2.2 did not trust the BIOS, ever.

try escape on LILO and

linux mem=zyzM

where xyz is somewhat less than the total mem (allowing for shared video etc), 
and of course somewhat less than 900M if you are hoping to install or use the 
standard kernel (use the enterprise kernel for more than 1G).

You might also try booting with one of the alt install kernels (Some of them 
are 2.2 based) and running an update, selecting kernel-enterprise as a new 
package to install.
