As another (probably useless) datapoint, I also recently
upgraded to 4.2-stable.  I upgraded all out-of-date ports
at the time, except I did NOT try to upgrade the vmware-
related ports.

Vmware seems to still be working for me, unless I try to do
a 'suspend' (the VMWARE option to suspend the running virtual
system), and then try to switch to a different system while
that first one is suspended.

In my case the X-terminal session is locked up, except that
the mouse can still move.  I *think* I could still switch
consoles via 'alt-opt-F1', but I did not have any sessions
in those other console windows so I couldn't do anything.
It would not even echo letters I was typing on the keyboard.

I did happen to have three remote sessions going via ssh
at the time, and those sessions could do some commands.
Once I typed in a "bad command", that session was hung.
Trying to pull myself out of this nosedive, in the last
session (which happened to be root), I tried to do a
'shutdown -r now'.  That session hung too.

In the end, I had to turn off power to the machine to get
it's attention, after which it booted up fine.

Also, in my case the virtual machines are 96meg, and the
real machine is a dual-processor P3 system with 256meg of RAM.
It is definitely NOT running into a low-memory situation...

I don't really have any time to help debug this right now,
but I'll be following it.  Maybe in a week or two I should
once again have some time.
