Yes, this will come... Probably, you have the patch on first post...
It seems qtopia Muromec find the good kernel sources for A1200, heh yes i hope for his health he got them from moto and didn't wrote everything form vanilla 2.4.20 !!
I'm still waitng for motorola to realeases better sources for A910... (for different reasons, sdhc has no sense on A910, the spi system on witch the reader is wired is too slow...anyway)
E6 users also don't have the kernel sources...
ext2 or ext3 support should be supported on qtopia, i never tested tho.
(by the way, this should be more modules than libs...i.e. the ext2.o file should be ext2 _module_ )
Strange thing, on my fw, there is no modules... O_o ? But i guess it's built in...Or it's this sdhc kernel...?
