hard lockup on nx5000 laptop with 2.6.11+hack and FC2's 2.6.10-1.770_FC2

[Ben Greear <greearb@candelatech.com>]

Several wierd things with my laptop since I upgraded from 2.6.9+hack,
which works beautifully.

1)  With 2.6.11+hack, compiled for the Pentium-M, the system
  freezes at or soon after I close the LCD screen.  Out of curiosity,
  I tried the FN - [F4] combination, which I believe should try to flip
  the video output to the external monitor port (I have nothing plugged in there).
  This immediately made the machine starting counting memory, and it turns out it
  had completely erased the BIOS settings to defaults and set the date back to
  Jan 4 of this year!

2) With 2.6.10-1.770_FC2 I totally froze the system when I tried to
  'ifup eth0'.  eth0 is BCM5705M (b44 driver)

3) When it freezes, the machine gets really hot, and the fan does not increase
  in speed like it normally does.  I am not sure if this means anything, but I thought
  I'd share it.

For now, I'm back at 2.6.9+hack, but I'm willing to try the newer kernels if someone
has a suggestion or needs more debugging.

Install is:  FC2, mostly up-to-date when I was having these problems, fully
             up-to-date now.
