If all of your data is in lost+found then, most likely, your root directory
was trashed.  Are you running a ext2 or a ext3 file system (or something
else).  If you're running ext2 then you need to switch to ext3, which is
supported on Slackware.

If it's all in lost+found, a first step probably would be to move the
top level dirs in lost+found back to /.

Clearly, your problems are either with a ext2 FS or a bad kernel.  I have
extensive experience with Slackware 10.0 and 10.1 and they are rock solid
with a single crash on about 5 system-years of operation.  (Sticks tongue
out at M$ users.)

Why bother with 2.6?  Yours clearly is unstable.
