problem with l4linux

hi, I'm sorry to trouble you,but I have a question with X server when start l4linux on dope. I have search a mail which you have sent:

Yes, I know that this setup is not easy. For overlay_wm driver to work it is necessary to apply patches to X Server sources, as I read. But I thought it must work with linux server with ordinary l4con/dope frambuffer driver. So, it won't, ok. -- When I checked on real machine (not with ramdisk), l4linux started and XServer starts OK.

I can start l4linux on dope and con,and also on serial console.The below is what I use in l4linux.cfg:

task "vmlinuz" "earlyprintk=yes mem=64M video=l4fb root=/dev/hda9 " all_sects_writable allow_vga allow_cli could you please tell me what I missing? thank you.
