We have done something similar on the gumstix but using Ubuntu on the 
gumstix. I am planning soon to test this with groovy.

The biggest problem for me was that data communication between ARM and 
X86 did not work properly if the message contains an uint8. The padding 
is different. This was if I remember correctly with fuerte. Have not 
tested yet if groovy have the same bug.

I am very interested reading more about peoples work with ARM.
