Wha?
Where did you get the "MB's" from?
I've got an eCos configuration for ARM that includes TCP/IP,
SNMP, Ethernet driver, serial drivers for 32 ports, real time
clock and watchdog timer drivers. The total for OS and all
drivers isn't more that about 256KB (text). If I add all my
application code and the GoAhead web server, SNMP server, and
some miscellaneous library routines I'm still under 512K.
I can add SSL and still be under 1MB.

Basic kernel w/o networking is probably in the 50KB-100KB size
depending on options and architecture. The single biggest
factor is network. You probably need to figure 128KB of text
and another 128-256KB of data for one of the BSD TCP/IP stacks.
