xset dpms etc... works for me, i.e. the monitor goes to low power mode.

Custom-compiled linux-2.6.16.5, but have had no problems regarding this
issue with several other 2.6.x linuxes, either debian and custom.

Do you use DVI or plain vga cable?
I have another box (an intel with a radeon 9250) connected to the same
monitor, through the vga port. Once I select that input (vga), I cannot
go back to the DVI one, where the mac mini is connected; I have to power
off manually the monitor (hard switch), because it freezes!
I'll supply you with any cfg files you may want to examine. Just ask.
