I tested this:
commit 9654640d0af8f2de40ff3807d3695109d3463f54
and see 2 issues:

1. After suspend to RAM, system wakes up but no screen.
I can log in through ssh though.
dmesg output at this point below.
Works fine on 2.6.20 and below, with same .config
.config and log file for this issue attached.

2. As a separate test, I enabled DynTicks in .config.
Seems to work fine but won't come out of suspend to memory at all:
pressing Fn/F4 seems to have no effect.

Do you believe that the second problem was caused by dynticks?

Assuming these are 2 different problems, yes, the second one seems
to be caused by dyntics.
