It appears that the MPEG card stole another interrupt what causes that
your modem (serial) interrupt got shared together with IDE controller
or some other mess. CHECK YOUR I/O AND IRQ CONFLICTS! Disable all the
braindamaged Plug'n'Pray stuff. Set it all manually to some valid values.
These messages shouldn't appear (of couse).

Yes this happens during machine crashes. Sometimes it is not fatal
as the first block of ext2 is unused. But your dump reveals that even
the superblock (and only it!) got damaged. Damaged are only the first 2KB:
first KB - unused (partly replaced by start of 16-bit FAT - huh?)
second KB - recoverable superblock
Use "e2fsck -b <value>" where value is 8193, 16385, 24577, etc. (k*8192+1)
And be sure that you have the latest-greatest e2fsprogs-1.10 as the
previous versions had bugs in "-b" processing (info from Martin Mares
<mj@gts.cz>).
And last but not least - it would be better to send images as MIME-encoded
binary - base64 (or uuencode).
