Boot memtest86 for a little while before booting the kernel? And if you

Indeed, that does the trick, thanks for the suggestion. So I can be
quite confident, now, that my RAM is sane and it's just that the BIOS
doesn't initialize it properly.
But I'd still like some way of filling the RAM when Linux starts (or
perhaps in the bootloader), because letting memtest86 run after every
cold reboot isn't a very satisfactory solution.
Bootloaders like to do things like run in 16-bit or 32-bit mode on boxes where
higher bitness is necessary to access all the memory. It may be possible to do
this in the bootloader, but the BIOS is clearly the correct place to fix this
problem.
