Keyboard/Bootloader Issue

[Strophios]

I own one of the last major revisions of iMac (not aluminum, the white plastic) and recently had to buy a new keyboard for it. The old white plastic keyboard being unavailable I bought the new, slim, metallic version. And it is a wonderful keyboard, except that, for some reason it does not work with my graphical bootloader. I currently dual-boot OSX and Ubuntu but because I am unable to choose which OS to boot to on start-up (because of my keyboard's lack of functionality) I have been stuck in OSX. If anyone has any ideas as to how to fix this they would be much appreciated.

Thanks.

make sure you have all the latest firmware updates.

I checked once when the problem began, but upon checking again I found an update specifically for the new keyboard... but it requires OSX 10.5, whilst I am still running 10.4. Looks like I'll just have to wait until I upgrade, whenever that it. That is, unless there are other ideas?

Thanks anyways though.
