I don't know what's up, but I tried installing a -CURRENT snapshot via a virtual CD "containing" the snapshot iso and got this behavior (I've tried several times on my laptop):
On most hardware you need to disable the use of "cmpxchg" to get -CURRENT to run in VMware at a non-zero speed:

I haven't seen the need for this on -stable, but it might be worth a try. We could do with a loader-tunable setting so that you don't need to build a custom kernel for installation in VMware.
Yes, that would be awesome. By the way, why "cmpxchg?" Does it have to do with VMWare not liking bus-locked instructions? How about the instruction prefix "lock" ? How is it handled by VMWare, anyway?
