I've been running VMWare 3 with FreeBSD for quite some time and have come to this conclusion.

Disable RTC, our rtc module hella sucks.  The difference of 92-99% cpu
usage on vmware and 3%.

Secondly enable AIO i've found a great performance and less crash happy
experience by doing so, make sure also you're using linux_compat and not
linux_compat8 that creates further problems unfortunatly.

Beyond that expect panics, I can get it to run 'once' flawlessly and
then I have to reboot my workstation or else the 2nd time I boot into
it, it WILL panic in mid-boot of Windows 2000.

and BTW,

RTC is only needed if you run Windows 98 for the 'fades' and 'effects'
so if you don't use them, kill the kernel module.  You won't miss much.

Infact it shouldn't be a dependancy since VMWare does NOT require it to
work.  It complains and gives you a hint to disable that
'complaint/hint'.  But nothing more.

Good luck
