Did you ask VMware to update this kb ?

http://kb.vmware.com/selfservice/microsites/search.do?language=3Den_US&cmd=3D=
displayKC&externalId=3D1006427

They need to have a FreeBSD section .=20

It's slightly sad VMware could. It figure this out . They have notes on disa=
bling hpet due to screwy clock issues under Linux , wonder why they never tr=
ied to disable it under FreeBSD  ?
