Strange. On my Ultra1, I have FB compiled in (Creator3D), parallel, SCSI
with logging, all RAID & LVM, a lot of networking options (iptables, IPIP,
GRE, netlink, fwmark, IPV6, QOS, Net scheduler, ...), PPP, PPPOE, ext2/3,
FAT/VFAT/UMSDOS, NFS client, module support, and my kernel is "only" 3.4
MB, and boots perfectly. Once gzipped, it is 1.4MB large.

David Miller is not the author of the SUN firmware. This limit is imposed
by the OBP.
