This commit breaks resume for me on an IBM ThinkPad X60 running i386 9.0.  
Removing VESA from the kernel again fixes resume.  On resume, I get this 
panic: http://people.freebsd.org/~gavin/IMAG0881.jpg .  I've tested it on 
head, and get the same panic with VESA in the kernel.  From the debugger, 
"show registers" gives:
  cs   0xc000
  ss   0x28
  edx  0x80
  esp  0xc1821fe8
  eip  0xe44f
  efl  0xb0202
with all other registers are zero.

Unfortunately, I don't know what other information I can get from this 
panic.  The backtrace gives no useful information, and the IP is not 
within kernel space.

BTW, this machine used to require hw.acpi.reset_video=1, but no longer 
appears to require this.  However, whether this is set or not appears to 
make no difference to the panic above.

Thanks,

Gavin
