since Three-Headed Dog has already passed the point of loading in ram on a 256 MB machine I'd see no problem with extra drivers in order to work on more hardware. Additionally, since it's using the same kernel as Slacko, drivers and firmware should work there too.And vice versa.
Go for it!

Normally, I'd vote 'NO' for any compact distro. However, this one is a pretender to greater, errr, greatness
YES - I vote for adding more firmware for networking (wireless)
I hear that. I will ask tempestuous and rerwin what they would recommend: what drivers and firmware to add to get the best balance between extra functionality and extra size. Maybe an increase of 5-7MB is just a first approximation.
