Ah, the GT, most evil beast.

Solaris up through 2.4 (SunOS 5.4) supports the GT.  I believe 4.1.4 will
work.

Question 1: have you run the GT self test?  Disconnect it from the host
card, set the switch to diag and watch the pretty pictures.

You need to enable support in the kernel.  If you want to use it as a
console (WHY???) then you may be out of luck, I'm not quite sure.  Only
the SS2 or SS10 was ever a supported host for the GT.

Does the card show up with a show-devs in the OBP?
