Well, I did know that, actually.  The problem is that when configured
this way using raw disks, the VM *won't boot*.  The configuration that I
had working in F11 before the disk rebuild had the controller type
changed to IDE because otherwise it doesn't work.

BTW, the CD-ROM shows up in VMware as being IDE.

I have a grub floppy image that I use as a boot loader for the VM.  The
boot loader starts and chains to the WinXP loader, then the VM hangs.  I
should point out that the WinXP system disk was not changed when I
repartitioned.  The grub on the bare metal machine dual boots just fine.
If I replace the controller type in the .vmdk file, I get a message that
the controller type is changed.  The boot starts, but it bluescreens.
