Sparc-10/81, OpenBOOT 2.22.1,
netbooting off Sparc-10/81 running NetBSD-1.5.1

NetBSD Gaia 1.5.1 NetBSD 1.5.1 (DebugNCR.4m) #14: Sun Feb  3 06:18:36 CET 2002     system@Uranos:/usr/src/sys/arch/sparc/compile/DebugNCR.4m sparc unknown

>Description:
OpenBOOT 2.22.1 does not seem to be able to come to a decision which
network port (AUI or TPE) to use. So I set boot-device to net-tpe.
The resulting boot path contains the following element with a three-
letter "partition" part: "ledma@f,400010:tpe". bootpath_build does
not handle this correctly. The consequence is that the boot process
stops asking for the root device with default "ledma0".
>How-To-Repeat:
On a Sparc-10 with OpenBOOT 2.22.1 (not tested with others), boot
using a boot-device of net-tpe.
>Fix:

The following hack seems to work for me:
