I think they're basically okay. I find it a bit weird that hvmloader 
puts SMBIOS tables in a fixed place and then rombios copies them -- not 
sure why that's needed but I suppose you're only copying what is done 
for ACPI tables. Couldn't hvmloader write all BIOS tables to a safe 
location and be done with them, or is the problem that 0xf0000 upwards 
is not available at the time hvmloader runs? Also, is the e820 
reservation entry actually valid: 0x9f000-0xA0000 is reserved, but 
rombios copies the tables out of that area, right? Does rombios also 
update the e820 table?
