Well, in fact I'd say "vive la différence".  It has the great
advantage of being able to cache up to 512 MB of memory, depending on
the tag RAM.  The TX maxes out at 64 MB.  You should check the tag
RAM, though (a small chip with the inscription xx129, xx256 or xx257).
You need at least two of them to cache more than 64 MB.  Also, the
Aladdin 4+ is about 3% slower than the TX with 512 kB cache, and
fractionally faster with 1 MB.

No.  Drivers are for peripherals.  The "chipset" is logically part of
the CPU.

I wouldn't call it pollution.  That's what the list's for.
