Yes, all USII based systems work fine with Debian gcc-4.9, as does 
T2000. Of USIII* systems, V210 and V440 exhibit the boot hang with 
gcc-4.9 and V480 crashes wit FATAL exception during boot that is 
probably earlier than the gcc boot hang so I do not know about V480 and 
gcc-4.9. V240 not tested because of fan failures, V245 is in the queue 
for setup but not tested so far.
