Thanks. it works well.
on ubuntu 10.04, 03eb:6124 is mapped to ttyACMx using cdc_acm
I compiled it the same way on x86 and amd64 (./configure
--prefix=/usr/local; make)
on x86, sam7 uses posix (sam7 -l /dev/ttyACM0)
on amd64, sam7 works with libusb directly
while connected, you have to remove ttyACM0 (rmmod cdc_acm), then it's
possible to use
sudo ./sam7 --exec set_clock --exec unlock_regions --exec "flash

once all set up, i'll write on the wiki.
