Ok kernel 4958 was around the time some NetBSD wide changes were made to
the ramdisc renaming it memory disc. As a result the 4958 kernel does not
correctly understand rd0a anymore (cannot remember offhand if just
specifing a root device of /dev/md0a may get round it with that kernel)

I woudl suggest trying a slightly earlier kernel say 4871 which is prior
to this change.

Ok the root floppy image is designed to be run from the ramdisc which is
why you get this error about the specified device not matching.
It happens when the install script tries to mount the root filesystem
read/write so that it can write temporary files.
