I guess an i486DX

no, not that option - only drop the FPU emulation! About the Pentium-Setting: we still have real i486 running Knoppix, slow but it works. As i486 doesn't give that much advance over i386 THIS doesn't help.

the 4GB-Setting, not 64GB!

as far as I know, it only prevents some problems if you have multiple devices with a high bandwith usage (as 2 USB-HDs)

it's only the "OSPM" - the power management...

hm... can't test (here both crash

It prevents several IBM Thinkpads from crashing on doing a suspend.
