Is there a way to disable one core of a dual core
cpu?

The Intel proset wireless stuff has a bug that
apparently fails to lock correctly and wedges
itself in some impossible state requiring manual
disabling and reenabling of the software to
recover. (The lock failure may be a XP problem,
or not)

If it's only one core, it won't fall into this
bug.

You can edit the C:\Boot.ini file to add
/numproc=1
and then reboot. For more info, see:
