[ltp] radeonfb sleep patch for kernel 2.6.15

[Guarded Identity]

Hi,

This reminds me of something I was curious about a while back.  At the time, i 
posted my question to a forum with really poor visibility... the "Discussion" 
tab on the wiki 
(http://www.thinkwiki.org/wiki/Talk:Problem_with_high_power_drain_in_ACPI_sleep).

Since my question still stands, I'll quote an excerpt of my post there:

I don't think that I suffer from the Radeon GPU problem, but it seems that 
with a little tweaking ACPI sleep can be improved.  Maybe someone here knows 
what the real limitation are.

I'm not sure whether the best place to discuss your sleep performance  is on 
this thread or on the wiki, so I'll leave that to you.
