As far as I know, no. Many of the complex functions (e.g. cexp) aren't 
implemented either, which can be a huge pain.

There was Altivec in 7.2-RELEASE as well, and it is quite stable. Ports 
that know about it will use it by themselves, or you can define 
something like CPUTYPE=7450 in make.conf to have the compiler try to 
autovectorize things.

8.0 has a bunch of other new PowerPC features like audio, SMP, G5 
support, ATA DMA, ADB keyboard and mouse support, some basic power 
management, including cpufreq, etc. Hopefully it will be a better 
experience than 7.2 -- the big architectural differences between 8.0 
PowerPC and 7.0 PowerPC have made it difficult to MFC things for some time.
