Like what? Did you file bug reports?

There are alot of reasons. While gcc-3.0 is currently superiour to
gcc-2.95 on alpha, it was not always so. Also, woody's been in freeze
(for awhile, unfortunately) and changing compilers at this stage would
cause more trouble than it would solve (for instance, all C++ packages
would need to be recompiled). Because of woody's (hopefully) impending
release, I didn't feel that changing compilers this late in the game was
beneficial to anyone.

Which drivers? Most of these can be worked around by removing the
optimisation or reducing it to -O0 for the affected drivers.

Most likely another optimiser bug. There are a few that apparently
generate bad code rather than bombing during compilation.

Bump/add any epochs in the package versions. That should make it so that
your packages aren't replaced normally by changes in the main archive
(unless the maintainers of the packages do the same, of course).
