Hold on Perderabo!
I'm not entirely sure your quick reply is 100 percent correct.
Linux drivers are written for GCC compilers. GCC compilers can create HP-UX binaries depending on the OS. See this link:
http://gcc.gnu.org/install/specific.html#hppa*-hp-hpux*
In the past, I have compiled lots of Linux code on HP-UX after installing a GCC environment on HP-UX, and I think that there are a few Linux/GCC drivers will port if written in GCC.
Now, that brings us to the question of version of HP-UX and OS; and as far as an
old HP B180 Unix Workstation with HPUX, it might be possible if it is running a version of HP-UX that is GCC compatible.
Then again, I have
no idea what version of HP-UX the B180 might have, or what RISC processor.... is it a version that is compatible with GCC?

Note: in 'the old days' when I used to write and compile code, one of my first tasks with a new client was to set up a GCC (platform neutral) development environment (for HP, Sun, IRIX, AIX, etc.) so I could use a much broader (and cheaper!) code base and lots of libs!!!
