[plug] xfree86 4.3 install options for Debian sarge?

[Daniel]

Hello All, 
I hope to use xfree86 4.3 to get one of the new chipsets going:
I could wait for the official deb package (how long does it normally
take?), do a manual install (necessitating a manual removal before any
later updating?) or try the unofficial site below for sid (will this
stuff up other dependencies?).  What's the best option?

Thanks,
Daniel.
