Hi, I am not the OP but I have the same problem, in my case affecting a Dell Latitude D830 running linux-image-2.6.26-2-686 (lenny). In fact for me the first CPU seemed to be stuck on lowest CPU frequency as well after I resumed.
I wasn't able to test with kernel 2.6.32 because, though it boots and suspends to RAM, it will not resume for me. I hazard a guess that some userspace tools might need upgrading from my Lenny versions. However I can confirm that the problem was already fixed in 2.6.30, as thanks to your hints I have now tested using the backports.org kernel 2.6.30-bpo.2-686, and suspend-to-RAM now no longer causes the second CPU to lose scaling. I think this is the applicable kernel bug: http://bugzilla.kernel.org/show_bug.cgi?id=10734 I hope the confirmation is useful.
