Chris, thanks for your posts!  I was trying to figure out whether apt
cached old packages, after all that googling to find an alternate source
for an older nvidia_bl I now see I have them all locally.  That is
useful knowledge!  I have flagged myself as affected by Bug #538329 as
you suggested.

Bug description:
On my MacBook 5.1, upon updating to nvidia-bl-dkms 0.16.1~karmic, the brightness controls fail to have physical effect on the brightness of the screen. The screen brightness remains at 100% brightness.

Pressing the brightness keys brings up the brightness indicator in the notifications area, and cause the brightness bar to move up or down very slowly (see Bug #357112), however this has no effect on physical brightness. Similarly, using the slider under System -> Preferences -> Power Management has no effect on physical brightness.

This is a severe regression. The 0.15 series was annoyingly slow to respond, but this new series doesn't respond at all.
