with 2.4 emulation all programs coredump? can you please compile -DDEBUG linuxolator
and send me (I'd prefer you put it on some web or somethign...) the debug output?

for kernel module you need some patches which are not in -current, just apply
http://perforce.freebsd.org/fileDiffView.cgi?FSPC=//depot/projects/soc2006/rdivacky%5flinuxolator/kern/link%5felf%5fobj.c&REV=2&ACT=edit

and "cd /sys/modules/linux && make -DDEBUG && make install" then plain kldload linux should work
but pls dont forget to -DDEBUG

thnx
