It turns out that on 10.6+ at least, just setting the button cell to enabled
does the trick:
NSButton *button = [window standardWindowButton:NSWindowMiniaturizeButton];
NSButtonCell *buttonCell = [button cell];
[buttonCell setEnabled:YES];
Still, it's definitely an Apple bug, and I'll file a bug report.
