Well, I'm not sure what kernel version you are using, but my first
suspicions would be that either

a)  the linux kernel in general is not working properly on your machine
b)  there is a memory hole somewhere above 256MB that is causing a 
    problem, possibly something like some card has a MMAP buffer that's
    overlapping with real RAM
c)  there is something wrong with your BIOS and how it inits that much
    RAM in terms of chipset setup

In any case, that the driver would work at 256MB or less and not above would
tend to indicate either a MMAP I/O space problem, PIO space problem, or some
other generic communication block as oppossed to a driver issue with how
much RAM is installed.  I think that I would check with either
linux-kernel at vger.rutgers.edu or linux-smp at vger.rutgers.edu and see what
they have to say about it.
