It booted into x and the desktop ok, but then completely locked up. I could move the mouse pointer, but no response to clicks or keyboard entries. I reverted back to the old kernel.
Yeah I had that issue as well as have several others both in the ##slackware IRC and on the Slackware forums. Here are some relevant comments that might assist you from the main LinuxQuestions.org discussion on the X lockup after the 3.2.45 kernel upgrade:

I'm considering doing a third build. If anyone who is running into problems still could revert this patch and rebuild to see if it fixes the issue, then I'd do it for sure. The only Intel graphics I have here are the trusty GM945, and there's no problem there.

and I was having issues with X freezing when using 3.2.45 (both the first and the second package), prior to switching to the 3.8.13 kernel from -current. However to help out with confirmation I'll revert this patch and compile 3.2.45 locally and try again.

Philip Lacroix wrote:Same as ruario here. I reverted the patch, rebuilt the kernel, reinstalled modules, rebuilt initrd, run lilo. After rebooting I didn't have any issues so far, so you probably fixed it. :)
@laprjns: So revert that patch and rebuild the kernel yourself and you should be OK.

There is now an updated kernel from slackware that should solve these issues.

Yep, I have replaced my locally compiled kernel with Pat's new packages and still no issues.
