The 2007 road map for the Ubuntu Linux operating system includes continuing its focus on the desktop, paying more attention to the server and garnering additional corporate support. Speaking at Ubuntu user conference UbuCon at Google's New York complex on Feb. 16, Steve George, director of support and services at Canonical, said, "The view from the Ubuntu side is that Microsoft has too much of the market. We're going to continue rolling out and making Ubuntu easy to use on the desktop and we'll add increased focus on the server this year."

I'm not sure if SuSE enables this by default. Ubuntu does, but some people say it's a security risk if someone has physical access to your computer (because they can kill processes/reboot it). Personally, I think if someone has physical access to your PC you're pretty much screwed anyway, and I prefer having the SysRq feature turned on.
BTW, you shouldn't do Atl-SysRq-B right away...for a safe reboot, you should follow the "Raising Skinny Elephants Is Utterly Boring" mnemonic sequence for the series of keys to press.
From the Wikipedia page:
"Raising Skinny Elephants Is Utterly Boring" is a mnemonic device for remembering a keystroke sequence that should be used as an alternative to hitting the power button if a linux system should ever "hang" and need to be rebooted.
1. Alt + SysRq + R -- takes the keyboard out of raw mode
2. Alt + SysRq + S -- synchronizes the disk
3. Alt + SysRq + E -- terminates all processes (Except init)
4. Alt + SysRq + I -- kills all processes (Except init)
5. Alt + SysRq + U -- remounts all filesystems read-only
6. Alt + SysRq + B -- reboots the machine
At the very least, you should always do "S", "U" and "B" (the "sub" sequence) to make sure disks are synced and unmounted before rebooting. If the keys do not work, and you know the SysRq feature is activated in the kernel, pressing Alt-SysRq-R should help give you back keyboard control.

Thanks for the link. I just tried Alt-SysReq-b and nothing happened though.
