ok... it's really monday... and i didn't understood that i must literaly 
write "module module module" :).

but now the error is another one. i've past that phase and i'm trying 
now to boot it properly using the cfg file.
with this menu.lst:

and here is the output. the error is in the last line:

but the file its on that path. the file its the loader script file to 
load the l4linux and contains this:

modpath "/home/tiago/fiasco_builddir"

sleep 2
task "vmlinuz.l4env" "no-scroll no-hlt l4irqack=linux root=/dev/hda1"
    priority 0xA0

and has this features:

-rwxr-xr-x    1 root     root          135 2005-05-16 11:01 loadercfg

so what can be wrong here?

thanks

Tiago
