>Description:
According to ACPI Specicication Section 14,
	14.1 INT15H E820H - QUERRY ADDRESS MAP
		This can be used in real mode only.
So it will not be expected to work on VM86 mode,and acctually ,
it do not work in my machine, used INT 15H E801H interface instead.
(In contrally ,there is a description that APM real mode interface 
accepts VM86 explicitly in APM spec.)

>How-To-Repeat:
Enable VM86 option and reboot your system and READ CAREFULLY First line 
of the message.
(not recorded in dmesg!)
>Fix:
Don't call the bios call in VM86 Mode.
If it is needed,use real mode call like non-VM86 APM  initialization.
