Airlink ar410w is not compatible with DD-WRT

Having just installed DD-WRT and then Tomato on a new Netgear 3500L, it was exciting to run a real OS on a router. I also had an old Airlink 101 AR410W still running, but upon checking it only supported WPA TKIP, not the newer WPA2 AES (avoid TKIP). I vaguely recall WPA being not that secure, and wanted WPA2. But there is no firmware upgrade from the manufacturer product page. I realized Tomato only supports a small subset of routers using modern CPUs, but could I upgrade to DD-WRT as it supports a fair number of routers.

A bit of hunting around shows that
  1. This router is the same as the DLink DI-624 which is specifically not supported by DD-WRT, in large part because it only has 1MB of flash, and you need 2MB just to run the mini version and 4MB to run anything full featured.
  2. The specs are it has a Atheros 2313 CPU + radio, Marvell 88E6060 ethernet switch, and Macronix/AMD 29LV800BTC-90 1MB Flash.
  3. The FCC ID from the label is: O7J-WLRT2454-QAO
In any case, it is clear I cannot install DD-WRT on this pre-2006 router.
