The PC is a typical desktop PC...it has 256 MB ram on the system. But
redboot is only reporting the following on boot...
RAM: 0x00000000-0x000a0000, 0x00088900-0x000a0000 available
>From what I read in the code, this means that the 0x00088900-0x000a0000
range (i.e., 96,000 bytes) is available to the user apps, which seems kind
of small. Specifically, I need a larger chunk of memory that can be used
by malloc (for elf loading).
I found another post in the archives that discusses adding another memory
region, but didn't know if that would be the best solution in this
situation.

I'd appreciate any thoughts you have...
