Subject: [PATCH] x86: alternative identifier for Phoenix BIOS

My laptop (a Samsung X20) contains a Phoenix BIOS and would benefit from 
patch 1e22436eba84edfec9c25e5a25d09062c4f91ca9 (x86: reserve low 64K on 
AMI and Phoenix BIOS boxen).

However, according to /sys/class/dmi/id/bios_vendor, the BIOS identifies
its vendor as "Phoenix Technologies LTD" (sans the comma).

This patch adds the approptiate identifier to the bad_bios_dmi_table in
arch/x86/kernel/setup.c.

The patch compiles cleanly and has been tested successfully on my machine.
