Subject: [PATCH] Phoenix BIOS fixup is needed on Dell Inspiron Mini 1012
Date: Wed, 31 Mar 2010 20:02:40 +0200	[thread overview]
Message-ID: <20100331180239.GA6732@twister.home> (raw)

The low-memory corruption checker triggers during suspend/resume, so we
need to reserve the low 64k. Don't be fooled that the BIOS identifies
itself as "Dell Inc.", it's still Phoenix BIOS.
