wont work. the slms motherboard is very very different than the fats.
the fats motherbaord is in 2 sections:
1)main baord
2)headphones+wifi+memory stick reader
while the slims motherboard it just one board with everything soldered on.
also, the video out wouldnt work for the follwoing reasons:
1)different locations
2)different sizes
3)psp slims is soldered on while the fat is on another part if the mainboard (see above)
and finally, yes the slim doesnt have the 1.50 kernel (not yet but people are working on that
)
but it looks like every application/game thats comming out now (homebrew wise) is supporting the slim and then hopefully it wll support the video out function.
