armv5tel support

[tlaronde%polynum.com@localhost]

Hello,

I'm new to ARM based machines and I have an already old Iomega NAS that
I would like to convert to a NetBSD based file and http server (it's an
experiment for now, not something I plan to put into production).

For now, the NAS has its original installation, that is Linux and here
is the dmesg (so that knowledgeable persons can hopefully tell me if it
can, in theory, be partially or totally supported by NetBSD):
