I presume you mean armv4t there, which the 920T core should support.
That's also the minimum requirement for EABI, since it mandates thumb
support (which is what the 't' stands for).

It's not possible to support EABI on armv4, which doesn't have support
for thumb instructions, but I can confirm that I've successfully used
uclibc with both OABI and EABI on a different arm920T chip.

Unless your Samsung unit is some sort of freak without thumb instructions
EABI should work on it just fine.  The main users I know of that got
burned by the EABI switch were some of the strongarm chips, which are
actually armv4, but afaik no-one is still producing products using them.

Cheers,
