Sorry for a slow response.  Basic questions:

 - what version of the kernel are you using?  (It would be a number like
   2.6.32-30 or so.)

 - does trying the kernel from
   http://people.debian.org/~benh/packages/linux-image-2.6.39-3-amd64_2.6.39-4~a.test1_amd64.deb
   help?

 - if not, does trying the kernel from sid or experimental help?

 - did you use previous versions of the kernel?  If so, which ones
   worked and which ones didn't?

 - could you attach the output from

	sh /usr/share/bug/linux-image-2.6.32-5-amd64/script 3>&1

 - could you attach full "dmesg" output from immediately after booting?

Thanks for reporting, and hope that helps.  (FWIW, this looks like
https://bugzilla.kernel.org/show_bug.cgi?id=22052 to me.  If that
guess is right, this should be merged with Bug#620848.)
