Nice review, and very well stated. Some comments
Windows Service packs require a few hundred megs of download from very fast servers. A 90 meg download to get working isn't that bad in comparsion
Instead of doing pidof gdm && killall <number> you can just do killall gdm
X can use plain old VGA mode when configured to use it. Infact, I think that's the default old of the box setting, but I'm not too sure. It can also use VESA modes, but they can get a touch slow ...
I do share your gripe about modems - although that's really down to hardware makers not releasing the specifications to make them work well. Especially WinModems .... which are essentially software modems. As they're software, there's a load of Intellectual Property locked up in the software which companies don't want to be open sourced, hence no driver. This is slowly changing though
