it's a pitty to hear that :~(

me too, but more RAM would make the unit behave better and give
it a little longer lifetime... NBD isn't an option to me because
most of the time there is no unix machine on the customers LAN
to get the swap :~(

having an 2MB or even 4MB flash would help if linux could
run in flash (i.e. uncompressed) like i.e. cramfs and jffs
do, instead of being expanded to RAM. I don't think this is
even possible but ...

(I remember ISA RAM expansions, for old machines. perhaps
one could use this idea to add a real bank of memory,
or even an RAM slot connector! then modify ALIOS do enable it
instead of internal RAM -- or am I going crazy?) LoL

port on SMC7004ABR V2 and me and others are working on
