While trying to use BT5 on Nokia N900 (you can see our attempts at http://talk.maemo.org/showthread.php?t=72933 ) sequel7 and I encountered problems running some tools (especially "john") and found out that although the distribution is compiled for ARM, the "john" tool is compiled for x86 and thus cannot be run on ARM cpus. I have encountered problems with other tools as well, but it was due to my microSD card being damaged. I will report here if I find more not-working tools compiled for other architectures (well, N900 is not officialy supported, but it runs and even can show desktop for few seconds at the moment... and we have working wifi injection drivers, so maybe it would be nice to support our beloved mobile computers? ).
