I am having trouble getting the kernel flashed, trying it from an Ubuntu 10.4 install.

anthonie@anthonie-laptop:~$ sudo ./flasher-3.5 -l -b -k meego-handset-armv5tel-n900-nokia-proprietary-1.0.80.13.20100803.2-mmcblk0p.raw
flasher v2.5.2 (Oct 21 2009)

Found device RX-51, hardware revision 2204
NOLO version 1.4.14

Anyone in the know that could give me some pointers?
