All the PCMCIA patches and hardware hacks available are for fixing a different hardware bug that only affects the A1200. AFAIR the behaviour you describe has been seen on certain A1200s with certain cards (there was a thread either here or on amigaworld.net about this). Maybe it would be fixed by one of the existing hardware hacks, but it might be risky because it's not exactly the same problem, and the A600 is thought to have no PCMCIA bugs. You might not have this problem if you use a different card.
