Under >=gentoo-sources-2.6.35, X mouse cursor is invisible - that is, its presence can be detected e.g. highlighting of form-fields on hover, but the actual cursor is not drawn onscreen.

this is known to arch too (I've seen it personally) https://bugs.archlinux.org/task/20373
The upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=29413 reports this as fixed with this patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=897493504addc5609f04a2c4f73c37ab972c29b2 which is in linux-2.6.35.6 which is in genpatches-2.6.35-9 which is used by gentoo-sources-2.6.35-r8 and later kernels. Can you please test with gentoo-sources-2.6.35-r9 and post the results.
Cursor has returned in 2.6.35-gentoo-r9 (skipped -r8), thanks.
Marking as fixed per comment #3.
