There are very few things in the kernel that we had in the SDK3
trial release that didn't make it into the mainline kernel in time
for Fedora 8.

These include:

* Support for perfmon2, which is still not in mainline
* Device drivers for running under systemsim, in particular the network
  driver.
* A bug fix for the SPE scheduler, which can prevent deadlocks when
  trying to use direct problem state mappings

There are also some configuration settings that are different. The kernel
from bsc.es uses 64kb pages instead of 4kb. This makes it performs better on
many low-level benchmarks but has a significant impact on memory consumption,
so you're probably better off using the Fedora 8 kernel.

In user space, Fedora 8 should be fine, but you may want to replace gcc and
gdb with the ppu-* packages from bsc for added functionality.
