I've only used preseed myself. Here are my parameters... this may be
where you're missing something:

initrd=initrd.gz auto=true priority=critical
url=http://yourserver/preseed.cfg console-setup/ask_detect=false --

I've always found preseed to be a bit of a headache as I've had to
result to trial and error to set some things up correctly - the
documentation isn't the greatest. In an event see how far that gets
you, and if you want more pointers with preseed I'd be glad to share
my preseed file.
