 have to be either sd or usb, i've extra sd/mmc so that can be done

 which one? analog or digital?  at the moment i've got I2S (5-line)
and SPDIF but if space is tight i could lose those and e.g. put the 5
pins of HP in their place.  if "digital" it's done (and there's enough
pins spare that i could drop down to FPC40), if "analog", which ones
do you want: MIC, FM, LINE, HP?  all of those is about 15 extra pins
so i'd have to lose say SPI2, and cut off half of TS and CSI (making
them useless)

 that'll have to be single-channel LVDS (handles up to... mmm.... 1280x800)

 there's a _few_ :)

 i've made it 45 but it could be down to 40... possibly
