Hi guys... just wanted to register to say a big 'thank you' for your help!

I followed uofamis22's guide and have a 540 working with 10.5.8

I'm tempted to try to upgrade to 10.6; I've failed to follow Crimson's 2HDD guide a few times, despite thinking I know what I'm doing. When I get to the OSX boot screen some text appears on top of it and then I get a note telling me to reboot.

My 8GB USB stick has gone AWOL so I can't follow dnicolaou's guide at the moment... may try at some point.

Odd problems with 10.5.8:

Zotac 9500GT reported as 512MB instead of 1GB after following uofamis22's meanderings to get his card working with hardware acceleration. I don't think this'll bother me much.

USB troubles - on some boots it fails to recognise my kb/mouse and I have to unplug/replug. Fix posted by dnicolaou for 10.6 doesn't work with 10.5.8 (no surprise!).

Sleep/wake not working.

Thanks again for all your help guys, very useful thread!
