Today I noticed that the nightly version doesn't do the auto-detect anymore (forcing ui.trackpoint_hack.enabled to 1 helps), while Firefox 5.0 works correctly. I'm using an old driver, Synaptics version 18.104.22.168, on a UltraNavPS2 device. I think that the reason is that the call to IsObsoleteSynapticsDriver was removed (which I was relying on) and replaced with a check for the Elan Tech driver. http://hg.mozilla.org/mozilla-central/diff/1d90c5f569a2/widget/src/windows/nsWindow.cpp This seems to be a different issue than bug 622410.
The change came from bug 640587, which is now on its way to Firefox 6.0
Yeah, the call to IsObsoleteSynapticsDriver should not have been removed as part of the bug 640587 fix.

Jo, can you test this tryserver build that has the IsObsoleteSyntapicsDriver call restored? Please try it without the ui.trackpoint_hack.enabled pref set. https://firstname.lastname@example.org/try-win32/firefox-8.0a1.en-US.win32.zip
Yes, this solves the problem for me.
Great. So I want to wait til I'm back in the office next week and verify I haven't broken the other scrolling hacks before requesting review.
Please see https://bugzilla.mozilla.org/show_bug.cgi?id=538189 for similar problems in Thunderbird 5.0 and latest-earlybird 7.0a2 .
Verified that this doesn't cause the Elantech hack detection to break.

Thanks for verifying, Jo!
