What does this mean, should I do anything about it?  Is tiling nice to have?

It sounds like GEM broke something - though maybe it just added a more 
verbose error report.

System: EeePC 701
Kernel: v2.6.36-rc1-5-g23cf24c
Chipset: Intel mobile 915G-something
Regretably necessary kernel boot option: noapic

I expect noapic explains the MSI failure.  I can boot without noapic if 
necessary for testing, but I can't run with it because I get nasty hangs 
& reboots.  I don't see why that merits an *ERROR*... anyway, what I'm 
interested in is the "Disabling tiling".

Thanks
Alan
