Comment(by Treviño):

 Well, I've tried again with a stable kernel from git
 d744c88c149269b95ec068c8615e492375415d6d that I've configured using the
 defconfig-2.6.24 and patched only with [http://folks.o-hand.com/andrew
 /linux-glamo-mpeg.patch linux-glamo-mpeg.patch] and
 [http://git.openmoko.org/?p=kernel.git;a=commit;h=5b9e0604ca4691782680e52cae6ffac32881a6b0
 fix-glamo-crank-memory-to-90MHz.patch]. Now suspension (well, it would
 better say "resume" since the phone has always gone into sleeping) works
 and I can resume the phone quite in all the tests I've done.

 So, the andy kernel branch has problems in resuming and I figure that
 they're due mostly to the patch:
 [http://git.openmoko.org/?p=kernel.git;a=commit;h=653f1f27b2c09b8f3ee1869f35ff6a0a50bb01b0
 fix-glamo-turbo-host-interface.patch]. In fact, if I enable this with my
 configuration I get a fps speedup (I don't know if it's only a placebo
 effect, btw :P) but the phone doesn't resume at all!

 I've just to say that the first suspension is longer than the others (I
 can check it turning on a LED, it takes some seconds more to turn off the
 first time). Is this a known issue?

 ''PS: this is not in theme, but I've to underline that the
 [http://git.openmoko.org/?p=kernel.git;a=commit;h=5b9e0604ca4691782680e52cae6ffac32881a6b0
 fix-glamo-crank-memory-to-90MHz.patch] fixes all the glamo hangups/freezes
 [http://lists.openmoko.org/pipermail/community/2008-August/027925.html I
 had using Xglamo].''
