Thanks for your reply. I'm running -current, so I'm really interested only
in wscons stuff. Machine is Ultra 5 (mach64 graphics).

For some unknown reason following code fails on sparc64 (but works on
macppc):

	fb_memory = (u_char*) mmap(0, fb_size, PROT_READ | PROT_WRITE,
MAP_SHARED, fb_fd, 0);

	mmap returns MAP_FAILED and errno is set to EINVAL. I double
checked everything, and I'm sure that fb_size and fb_fd parameters are
fine.

Any ideas?
