yes it does... that is the only problem I see in your configuration...
ie I believe the 'stock' kernel is configured as 1 gig max physical
memory, leaving 3 gigs for max process virtual address space. you
have to live in the X+Y=4gigs, where X=phys memory, Y=max process
virtual memory. And to use other than 1+3 you have to modify the
source code.
Xeons support a 36 bit address space, but I don't believe anyone has
fooled with that for linux yet...
I put together a quad xeon for roughly this:
4200 bucks for the Intel SC450NX chassis...
1000 bucks for each of 4 xeon cpus
1000 bucks for 1/2 gig of memory although this might have changed
700 bucks for each 9gig 10Krpm LVDS IBM drive.
It runs like a bat out of Egypt... and is so fast I often don't even
have to press the <return> key... it just 'knows'. :)
