define 'doesnt work' :-)
does it just lock up? at what stage? what hardware is in the box?

try unloading some drivers before you do the suspend.
(the pm-hibernate script will do this for you, but if you do it
 by hand, you should be able to narrow down which driver is causing
 the pain).

Jeremy and I did try an SMP kernel once, and it didn't work for us
either, but we didn't investigate it further.

File a bug on it, with as much info as possible, and we'll see
if we can get it figured out.  With the advent of HT & dual-core
CPUs that will inevitably end up in laptops at some point, we
have to make sure that SMP works too.
