Mine doesn't, although I hear it's possible to open up the case and solder 
one to the board.  That's not my goal however.

Nice, so the kernel and package support is there, good.  That's the main 
thing I was concerned with.  My specs are almost identical, I have half 
the ram you do, probably a slower processor (~85MHz), and, as mentioned 
above, no USB port.

I'm not so concerned with the storage issue.  My "grand design" includes 
having the image on flash pivot_root onto nfs or nbd/iscsi/ataoe.  Once 
you get off the flash it's size stops being an issue.

I know debian-installer isn't going to be able to do this automatically, 
but I'm interested in a two-stage boot process (similar to using and 
initrd or initramfs for LVM /):
1) RO Squashfs image for inital boot (the same way the OpenWRT setup goes).
1a) Configure the vlans (settings from nvram)
1b) Bring up the lan (settings from nvram), but leave all other interfaces 
1c) Start a dhcp server (may need to mount a small ramdisk to save leases)
1d) Start any other services (like portmap) needed for (1e).
1e) Enter a loop that waits for my desktop to expose nfs,nbd,iscsi or 
1f) Mount the /real/ root
1g) Copy leases over, and shutdown dhcp server and any other services that 
don't have to stay up (e.g., I think I can shut down portmap at this 
1h) pivot_root into new root and start /sbin/init for the full debian 
system and unmount all the stage 1 filesystems.
2) Debian-mipsel system
2a) iptables,ip6tables,6to4tunneling,qos,etc.
2b) Bring up all network interfaces.
2b) opensshd,openntpd,etc.
2c) apt,etc.

Since I won't be reusing binaries between stage 1 and stage 2 I was going 
to use uclibc or even klibc for stage1 but run a full glibc in stage 2.
