How much memory is in the machine by the way? And Andrea, is the
vmalloc space size reduced in the 3G user space configuration?

it's not reduced, it's the usual 128m.

BTW, I forgot to say that to really take advantage of CONFIG_2G one
should increase __VMALLOC_RESERVE too, it's not directly in function of
the CONFIG_2G.

So how much do you recommend increasing it?   Currently it's:
include/asm-i386/page.h:#define __VMALLOC_RESERVE       (128 << 20)
include/asm/page.h:#define __VMALLOC_RESERVE    (128 << 20)
