sun4c "memory address not aligned" seeming bug

So I'm having an interesting problem netbooting an IPX with a snapshot kernel (downloaded from ftp.openbsd.org yesterday).

ok boot net

SPARCstation IPX, No Keyboard
ROM Rev. 2.9, 64 MB memory installed, Serial #2218979. Ethernet address 8:0:20:1a:b:31, Host ID: 5721dbe3.

Rebooting with command: net
Boot device: /sbus/le@0,c00000 File and args: 12200
>> OpenBSD BOOT 2.2
boot: client IP address: 10.1.4.6
boot: client name: luke
root addr=10.1.1.200 path=/export/netboot/luke/root Memory Address not Aligned
Type help for more information
ok

So googling for this, I find (surprise, surprise) a netbsd bug reported in november, that mostly seems to be resolved to "its a sparc bug":

http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=19019

Is there any way to fix this on our end? Presumably, if its related to kernel size, somebody booting a snapshot nightly should be able to spot this (as, in fact, I was doing until a couple weeks ago when I stole a disk off this particular machine; I am trying to get it set up to do nightly builds again now). Would it be possible to produce a meaningful error from the kernel before the sparc spits out this "Memory Address not Aligned" error?

Thanks,
