Of Course, It Runs NetBSD!™

NetBSD boot was almost a piece of cake. It tries to detect more things than Solaris and Linux, so I had to implement a couple of device registers more. At the first glance using more registers contradicts with the declared portability. On another hand, it would work on some modified/weird chipsets having non-standard interrupt controllers. Don't know if such chipsets were ever produced though.

Haven't found any CPU bugs so far, only interrupt processing in the serial port (not relevant to [Open]Solaris). Surprisingly sparc32 and sparc64 serial drivers diverge quite a lot.

Next stop - FreeBSD/sparc64.
