Sorry, just got off a long flight from San Diego to Singapore. Anyway,
slow ... means that even without vmware, if I just hit return, the lines
would scroll for about every 10 lines and there'll be a litte pause (<0.3
sec). With pre6, there's no such behavior, and if CONFIG_APM_CPU_IDLE is
not set, the "pause" goes away.

"host" system is linux. "guest" system is linux (actually, I tried with NT
as well, same problem).

The sympton is when I try to ping the "host" from vmware's "guest" system,
the first response came back to the guest's console. Then if I don't type
anything or don't move the mouse on the guest's console, I won't see any
further response on the guest's linux console. Even with a lot of mouse
movement or pressing the keys, the response is still very slow with "ping".

If I ping from the "host" linux console to the "guest" linux system,
responses came back, and does not hang. I'll double check this last point.
Got to recompile the kernel again.
