Hi,
(I cross-posted this to devel as this is interesting also to
them. When replying, you could remove e.g. "users" list as
I don't think this applies that much to normal users anymore.)

This doesn't make /media/mmc1/ writable by everybody.
(Busybox mount sucks?)

This works:
umount /media/mmc1/
mount -t vfat -o
rw,nodev,nosuid,utf8,uid=29999,shortname=mixed,dmask=0000,fmask=0133
/dev/mmcblk1p1 /media/mmc1
Check also that:
ulimit -c unlimited
is run before DSME[1] in linuxrc (on initfs).
[1] which (re-)starts the dnsmasq proccess along with many others...
