Did my first successful sparc32 install last night, on the dual SS20. Swapon still segfaults on sparc32 SMP kernels, but its not a showstopper. Parted still complains that the number of cylinders on the disk label don't match the geometry, but fdisk doesn't have any issue. I'm sure this is parted brokenness, because on the ss20, it was able to make/format partitions without issue. Videocard probing doesn't work at all on sparc32 right now, but on the good side, I'm pretty sure that I managed to fix SCSI & Network Card detection. Going to try to check that later this morning.
I'm might try to make another beta release sometime within the next week or so, likely just isos.
