Its been running since 1.3.4x just not merged. The corel NC is Linux/ARM too
There are several ARM chips that may be attractive to a pocket computer -
more likely the cirrus 7500 would be a better choice (or 7100 even) than the
SA110. Its slower but has onboard peripherals and LCD drivers.
[Is it a digital, intel or compaq StrongARM nowdays ??]
