"Perhaps the suspend script can check for the presence of the fglrx
module and refuse to suspend in that case... (with a comment documenting
this)"

That's a pretty drastic solution to the problem, considering that it's
caused by premature commitment to a brand new kernel feature (the SLUB
allocator), particularly for a distribution with a reputation for "it
just works" and "user friendliness".  It's been confirmed both here and
in the several duplicate bug reports that restoring the expected
behavior (normally functioning suspend/hibernate/resume) is a simple as
switching back to the SLAB allocator.   Everything works again, and
nothing seems to break.  I haven't found a compelling argument for SLUB
over SLAB  yet other than "the simplified code is attractive" and a
*claimed* "5-10% performance increase" (Emphasis mine - where are the
benchmarks?).

Given that defaulting to SLAB until SLUB has been more widely tested is
unlikely, it seems that a solution that doesn't put undue burden on the
user would be preferable to the workarounds mentioned so far.  Something
like having the fglrx package depend on a SLAB version of the kernel
(installed alongside the default SLUB version) along with a note to the
user to boot into the SLAB kernel if they need suspend/resume to work
with fglrx.  Once it's been confirmed that a future version of fglrx is
compatible, the extra dependency can be quietly eliminated.
