As I said somewhere on IRC before, it might be worthwhile to bump the default drive-strength at some point, but so far it seems the minimal needed values seem to diverge (8mA on Veyron, 12ma [4mA on mine] on firefly and seemingly 4mA working fine on the Rock2). So I guess we'll postpone that a bit more until we have more datapoints ;-) Heiko
