I use S3 (suspend-to-ram) and S4 (suspend-to-disk) without any problem since 2.6.12 (or before, I don't remember), directly from X.org with the FLOSS radeon driver (and with all the driver but the modem installed, included the ipw2100). And the machine survives to multiple sleep cycles :-D I've never tried suspend2, because the vanilla ACPI is working perfectly.
