i have a mac book pro ( 15 inch, 2.4ghz, late 08)

the memory limit is 4 GB. Is this an OS limit which will be blown away with snow leopard, or is it a hardware limit, which will remain regardless of 64bit OS?

other MBPs have 6 or 8GB limits, which makes me think they may be hardware related
 
It uses Santa Rosa chipset I think so it's limit is unofficially 6Gb. It's not software related, your MBP's memory controller can't handle more than 6Gb
 
The PM/GM 965 chipset has a 8 GB address ceiling but for some reason Apple doesn't allow you to address more than 6 GB.

Unibody macbook, doesn't have santa rosa, or any centrino for that matter i dont think. NVidia hardware instead.

Dell had mobile workstation with 8GB on offer with the same chipset. So it I assume, it is an artificial limit by Apple.

Has someone tested the Mac hardware with 8GB under Linux?
