Well, yes and no.

First, E911 is a US program, so obviously it doesn't apply anywhere else.

--Simplified Explaination--

The E911 program mandates cell carriers increase the accuracy of
cell phone location.

The program is implemented in phases.

In the intial phases, carriers have the option of either increasing
their triangulation accuracy or going to GPS phones.

Some carriers have chosen one method, some the other.

The majority of the major cell carriers chose the GPS method.

Here's some timetable stuff from the FCC:

Nextel: by Dec 31, 2005, 95% of all handsets must be GPS.
Sprint: by Dec 31, 2005, 95% of all handsets must be GPS.
Verizon: by Dec 31, 2005, 95% of all handsets must be GPS.

ALLTEL is also going GPS, but I can't find their schedule.

It is now 2007.

It is getting difficult to get a cell phone without GPS in the US.

All the details are at http://www.fcc.gov
