I think you have mistaken two different issues. The "Trusted Computing" issue
is separate from the digital restriction issue on the PCIe / wifi slot. The
"Trusted Computing" issue is more so about entertainment and control of ones
hardware.
The simplest work around is to go with in this instance is a USB G wireless
adapter. This isn't really a great solution as you can't install a USB
adapter inside the laptop like you would a normal wireless card. However it
will allow you to re-gain Internet access and usefulness of the system. The
only adapters which will work are those with RTL8187B, RTL8187, RTL8187L, and
AR9170 chipsets. At least 'out of the box' right now. They should work with
all recent releases of Trisquel.
You can get one of these Penguin Wireless G USB Adapter for GNU / Linux from
us here (better to go through libre.thinkpenguin.com though as 25% of the
profits then go to the Trisquel project):

If you wanted to upgrade to jxself's kernel (also maintaining Trisquel's
kernel) and install the ath9k_htc_open firmware you could do that also and
get a USB N adapter. In that case get the Penguin Wireless N USB Adapter for
GNU / Linux (TPE-N150USB).
