FreeBSD 6.0-BETA3 panic: vm_fault

I have a low end DELL Lattitude that has been successfully
running 5.4-RELEASE.   I have tried loading 6.0-BETA3 three
times and it panics every time early while loading the Minimal
system.  Does anyone else see this?  (I haven't ruled out a disk problem)
Hand transcribed from the screen:

panic: vm_fault: fault on nofault entry:
c7229000 cpuid = 0  
[thread pid 26 100026]
Stopped at kbd_enter_0x2b: nop

For the install process, I pick
"Standard", Give the whole disk to slice1 for FreeBSD
and take the "Auto" partitions.
I ask for a "Minimal" install.

(side note:  the new default partitions sizes seem strange:)
  1a /     512MB
  1b swap  230MB
  1d /var 1139MB
  1e /tmp  512MB
  1f /usr  708MB

I retried loading 5.4 Release, and it successfully installs.

Here is the dmesg from a working 5.4-RELEASE
