I'm having the same problem -- last character of my ESSID is being dropped with 2.6.20-16. Using linux-image-2.6.20-16-386 and wireless-tools-28-1ubuntu3; all packages current as of today for Feisty Fawn / 7.04.
If I boot into an older kernel (linux-image-2.6.17-11-386 (same system, not changing any other packages), this problem goes away. (Unless I've implemented the extra-character workaround in /etc/network/interfaces, in which case the problem comes back, but anyway....)
Interestingly, just after the upgrade to Feisty Fawn, the r818x (and the ieee80211-rtl it depends on) module no longer loads automatically. A simple "modprobe r818x" fixes this, but shouldn't be necessary. No evidence yet this is related to the ESSID truncation.
