Maybe I'm mixing things, but if VMware is capable of running on a i586
(=P5?) (like AMD K6 - and it certainly is capable of doing that),
should not VMI be similar?

For example, the TM5800 CPU which is somewhat of a mixture between i586
and i686 but does not have an IOAPIC can run VMware machines (although
painfully slow).

And, the last thing, distributor kernels are often compiled for i586 to
be generic to all users. But some users may actually run them on i686,
and these users would like to have VMI (speculation :-). Which would
include a forceful patch to Kconfig to have the VMI option available
with CONFIG_M586.
