I bootstrapped my Ultra-1 last night with NetBSD 1.5 using Solaris.
	I am very happy that is much more responsive than Solaris 2.8 <gag>.

	I'm working on applying ALTQ patches to my kernel to do bandwidth QoS.
	While rebuilding the GENERIC kernel (without patches, yet), I get a 

	floyd: {67} make
	cc -g -O2 -Wimplicit -Wunused -Wswitch -Wcomment -Wtrigraphs
	-Wchar-subscripts -Wparentheses -Wstrict-prototypes -Wmissing-prototypes
	-Wpointer-arith -Wa,-Av9a -mno-fpu -I. -I../../../../arch
	-I../../../.. -nostdinc -DSUN4U -DTRAPWIN -D__ELF__ -DLKM -DDEBUG -D_LP64
	-DMAXUSERS=32 -D_KERNEL   -c ../../../../kern/vfs_syscalls.c
	/var/tmp/ccEYd6hn.s: Assembler messages:
	/var/tmp/ccEYd6hn.s:322: Fatal error: Can't extend frag 98. chars
	*** Error code 1

	Trolling the list, I find that installing a new toolchain will fix this
	problem. I looked at the ftp site, and there are a couple toolchains
	available now.

	Which one do I get? Would a later snapshot be better, -current, or?

I'd say get the latest toolchain.  I think it should work with 1.5.
