question about extlinux.conf on flashstick with ext2

Hi ,
I ve tested the pclinux minime on usb 1Gb and later 8Gb, with fat32 and syslinux boot , works splendid in Ram , and persistant saves on stick..
Now i want to try extlinux-boot with ext2 or 3 on the usb.
With ext3 , i get constantly bumped to commandline, where i could type in the vmlinuz and initrd paths , but it cant make the loop-file of minime work..so it gets little panic :*
But it wont read the extlinux.conf in /boot/extlinux on sda1
With ext2 somehow it reads and finds the extlinux.conf - but after
vmlinuz and initrd - it bumps back to reboot...

Done in short steps with other linux boot, where sdb1 is the usbflash:

mkdir /mnt/sdb1/boot/extlinux
xxx/extlinux361/extlinux# extlinux --install /mnt/sdb1/boot/extlinux
umount /mnt/sdb1
xxx/extlinux361/mbr# cat mbr.bin > /dev/sdb
mount /dev/sdb1 /mnt/sdb1

edit and save a /mnt/sdb1/boot/extlinux/extlinux.conf (last version) :
default liveusb
prompt 1
timeout 50
label liveusb
kernel ../vmlinuz
append livecd=../livecd initrd=../initrd.gz root=/dev/rd/3 vga=788 keyb=us bootfrom=/dev/sda1 changes=/dev/sda1/changes fromusb

edit:
*livecd= , *root= , *bootfrom= , **changes= , **fromusb comes from syslinux.cfg
and
*partly worked in ext3 different commandline-tryouts , but all ended shortly after the loopfile

It feels like this extlinux.conf is kinda right way - but can i get further? with minime and ext2 /3 and the livecd.sqfs it uses ?

That's somewhat odd. When you say "wont read", can you explain what
happens? Is the right partition set active?

You get bumped to the command line because you have "prompt 1" in your
config file, I presume you already realized that.

Your command line is full of arguments which appear specific to your
distribution (minime, I guess), including stuff like /dev/rd/3 which is
old devfs syntax.

I don't think what you're having here is a syslinux problem, as it
appears to bootstrap everything.and I don't know if you'll find anyone
on the list familiar with your specific distribution. You might want to
ask in a minime forum.
