..yup, my understanding is motion "more than prefers" mmx, the
k6-2 cpu offers mmx hardware and the i486 kernel does not offer
support for mmx hardware, so those mmx jobs are instead done
emulating mmx in ffmpeg userland or somesuch, googling "mmx
ffmpeg" shows a fair bit of disussions around these 2 around
A.D. 2005 thru A.D. 2008, so plan A is a k6-2 kernel. ;o)
