... or if you will be running a distro that has the driver installed
natively sometime in the next 6 months.

Indeed.  I have no illusions that the open-source radeon driver will
magically acquire flawless suspend/resume just because better docs on
the chips exist. However, it is better to have the HAL functionality in
place to handle things properly when we have a shiny new kernel driver
written basedon the docs that does have decent suspend/resume support.

It is not so much "optimization" as "not actively ignoring them".
Currently, I see HAL as doing the latter on Linux. The freebsd code
seems to be doing a better job there.
