According to a recent thread here cross platform pbuffer support is
being added to SDL. Hopefully Sam will pop in and give you more details.
But, you migth try looking at the archive and looking in the CVS code
for it.

AFAIK pbuffers are pretty much the only solution to the problem. 

Hope that helps,
