I have a U5 running NetBSD/sparc64 and NetBSD/sparc dual boot on
separate disks. NetBSD works well on this platform.

Yes, GCC is buggy. There was a file in the kernel source that triggered
a GCC bug also...

BTW: This is a fault of the fpa(4) driver. When I ported the PCI support
from OpenBSD/hppa to NetBSD/hp700 I found at least one source of that
problem. So fpa(4) doesn't work on hp700 also. Unfortunately I can't fix
this due to ENOTIME and ENOCLUE about fpa(4) internas.

Yes. You can compile a 32 bit sparc64 kernel and run a sparc userland.
There is no sparc kernel that can run on sun4u CPUs. The sparc for sun4u
kernel configuration is just a reach over to the GENERIC32 kernel config
of the sparc64 architecture.

BTW: If you want NetBSD and firewire you may want to try the port of the
FreeBSD firewire code. There was somthing about this on tech-kern...
