Thanks Hin-Tak, I haven't checked your answer yet. When I have got an
answer I' ll post here. But I have to say that I' ve compiled (Ubuntu
8.10 distro based) compat-wireless without uninstalling
linux-backports-modules-2.6.27-11-generic and rtl8187 works correctly.

In order to installing compat-wireless rtl8187 driver I' ve done a
shell script to automate compilation process but next
step should be create a .deb package to include this in a repository
tree. Do you know if is there one with stable rtl8187 driver yet
(2.6.27-11)?
