For your Alphas?  I have a solution!  :-)

I'm about to upload a new binary snapshot for NetBSD/alpha.  You should
be able to fetch it with passive FTP (the default mode of NetBSD's ftp(1)).

I will upload source for my snapshots after I upload the alpha binaries.  I
also uploaded an i386 binary snapshot yesterday.

Give me a chance to get rid of the obj.{i386,alpha} directories, then
I'll tar up the source and u/l it.

For the install process, the new kernels don't allocate receive buffers
until you ifconfig the interfaces up.  Also, on the Alpha, you can increase
the number of mbuf clusters on the fly with sysctl:

frau-farbissina:thorpej 320$ sudo sysctl -w kern.mbuf.nmbclusters=2048
kern.mbuf.nmbclusters: 256 -> 2048
frau-farbissina:thorpej 321$ 

Sorry, can't do this on i386 because it doesn't have a KSEG.

Do do the update, at least on i386, you're doing a a.out->ELF transition.
It might be easier to just use the `upgrade' feature of the install tool.
