ODDie is basically correct.  It turns out to be an error in the linux-
input kernel commit for the Bamboo Pen in wacom_wac.c.  The pressure is
erroneously set to 255 instead of 1023:

static const struct wacom_features wacom_features_0xD4 =
        { "Wacom Bamboo Pen",     WACOM_PKGLEN_BBFUN,     14720,  9200,  255, 
63, BAMBOO_PT };

A submission correcting the mistake will be made shortly to linux-input.

In the meantime on Natty you could use the wacom.ko from input-wacom.
HOW TO compile and install it is described on the Bamboo P&T HOW TO:
http://ubuntuforums.org/showthread.php?t=1515562  or the Linux Wacom
Project mediawiki site.

Or you could use Irie Shinsuke's PPA which uses input-wacom and is
linked on the HOW TO.
