A few notes:
- Installing on 32bit is unsupported, but you could in theory still do it as I
don't thing we block this. This configuration is not advised.
- I am looking into a better way of providing source packages for open
components. I might just make a PPA but design is pending.
- We do not support --no-dkms with --pro, granted this should be documented but
is likely not.
- PX should be marked as deprecated in the installer, this is likely not yet
documented correctly.
- I'm aware of the mesa dri post install script issues. I pushed some fixes,
but I'm not sure which build it landed in.

Will try to address the individual bugs if I haven't done so already.
