I've also had a similar laptop model with A8-5550M and FreeBSD worked more or
less fine on it.  I've described my experience on our wiki:

You're right, it's a known problem with HP laptops, native 1366×768 resolution
probably won't work.  Try 1024×768 instead by dropping to the loader prompt or
putting "gop set 2" line into /boot/loader.rc.local file (note that it might
not work with Lua-based loader(8) per bug #235040).
