The realbtx.2.patch does not fix the hang during boot of my HP Pavillion
dv9420us.  The boot stops just like before, right after the Copyright
message and text=?????? it freezes and only a power cycle will bring it
to life.  Currently, I work around the boot hang by pressing <spacebar>
starting just before the BIOS splash disappears; and then press <enter>
at the boot slice prompt.
