Work continues on sparc32 (I've focused almost entirely on it since my return from LinuxWorld).
Several stupid mistakes were present in the sparc32-BOOT kernel. Hopefully, I've got them all cleaned out now.
Also fixed the issue with serial installs not having ttyS0 in /etc/securetty (new setup RPM) and fixed the lingering tty bug in anaconda. Now, I'm just waiting for the kernel to finish rebuilding, and I'm going to do another sparc32 ISO spin. No, you can't have it now, its REALLY not ready for prime time.
Oh yes. I also re-enabled RAID5 in the BOOT kernels, and demodularized usb-ohci in the sparc64 BOOT kernel to see if it makes the keyboard magically work (since including the module in the initrd did NOT do the trick, as hoped). But I'm going to hold off on a sparc64 respin for a little while, so I can focus on sparc32. Maybe tomorrow evening.
