Nah, don't worry:
1) Linux has already a patch against it (2.0.32-pre5, soon to be 2.0.32),
2) Intel has been estonishingly linux-friendly (Linux went to their
headquarters discussing the linux patch, they mention Linux on the
web page they devoted to the bug)
3) NT is not multi-user, it's sequential multi-user (and even that, badly).
I mean, you cannot telnet onto an NT box and crash an other user session
(hence sequential). Furthermore, IMHO, it doesn't need a pentium bug
to crash it.
