Lucky you! That's because almost two years (or so) of heavy work by many
people went into this. Also, you're probably lucky with your Thinkpad.

When I bought this laptop (a Sharp Mebius PC-MT1-H5) back in Sept 2001,
there weren't many machines on the market that had only ACPI (and no
APM). And Linux ACPI wasn't in a very sane state back then, not to
mention swsusp. It took almost two years for the software to mature, and
only recently did I get a stable machine that I can work on for a month
without rebooting (suspending/resuming several times a day).

I've just gotten a Centrino-based Toshiba Dynabook SS S7/290LNKW, and
the story continues -- I've already hit at least two ACPI bugs, while
swsusp problems seem to have been ironed out thanks to hard work by
Nigel Cunningham. And of course, the built-in wireless card does not
work. My guess is another 6 months (if not more) until Linux works on
it.
