Thanks. I've added a comment to the bug:

First off, of course you are encouraged to re-test with 3.0-rc6 just to
make sure it hasn't changed in some way. I don't think anything has
changed enough to affect this, but it's always good to be sure.

I note a long sequence of patches that are supposed to help with the
U160:

448f53a1ede54eb854d036abf54573281412d650 drm/i915/bios: Reverse order of 100/120 Mhz SSC clocks
bcfbbce822d219eb587acaba8a6e062bbeae4761 Revert "drm/i915/bios: Reverse order of 100/120 Mhz SSC clocks"
a76150302d6e7ebc43e1a1ddaee7fd51db8da3b3 drm/i915: Add a module option to override the use of SSC

I'm not sure why a quirk wasn't added for this hardware; it's clearly
'non-standard' in some mystic way.
