[ECOS] Running eCos from PLCC EEPROM?

Has anyone looked at loading eCos from PLCC EEPROM (from a boot loader
such as GRUB2)?
1MB+ PLCC chips are now pretty cheap, and based on my research it
seems like a useable eCos install can be considerably smaller than
that.
My particular interest is that GRUB2 is now booting directly from PLCC
on the Lemote Yeeloong [1] a MIPS64 compatible netbook. However many
useful features such as support for the rtl8187b network card in the
Yeeloong are in development and may not be stable for some time; if an
option could be to boot to eCos from the same PLCC chip that GRUB2 is
installed to, that would make for a really flexible system for doing
whatever with the system from that point on (eg much more so than
PXE).
