Gotcha!... in a strict technical sense, the old ABI ws also a variant
of EABI, just to keep things truly confusing, and a few programs still
insist on calling it that - only humans don't.
See the section "GCC view" in wiki.debian.org/ArmEabiPort for how to
tell them apart really.
"arm-linux-gnueabi" is the unambiguous term we should use I guess.

Is what (new) EABI binaries load with (.2 is used by old-ABI binaries)

With an old-ABI Etch root filesystem you will still need to use one of
the above tricks.
If you're feeling brave, replace it with a pure EABI root filesystem,
like the forthcoming "armel" Debian port, which is still under
development but is at the point of being quite usable, with relatively
few problem packages, mostly the esoteric languages.
That'll give you full FP speed in everything.
See wiki.debian.org/ArmEabiPort and the HowTo subpages it mentions on
the first line.
EABI with old-ABI compatibility running old-ABI userland is
suboptimal. If you use an EABI userland and compile your own kernel
with old-ABI compat turned off, you get a further performance increase
on every system call.
