Why don't you just use the F() macro...
I get this compiler error every time:
Greenhouse123:237: error: invalid conversion from 'const __FlashStringHelper*' to 'int'
Greenhouse123:237: error: initializing argument 1 of 'void ETHER_28J60::print(int)'
Unfortunately, class ETHER_28J60 does not inherit from class Print, which means that it can't directly print F() strings.
