Upstream coreboot and mrchromebox's coreboot, which do support loading Linux
natively or with UEFI, both use capitalized GOOGLE as DMI System Vendor
as far as I know.
By the way, the shipping BIOS (coreboot customized by Google) does not support
mainline Linux natively (eg. without seabios and nasty tricks), but only
Chromium OS, which for Caroline is an old 3.something fork of Linux, so this
patch does not really apply to Chromium OS or to Linux running on shipping BIOS.
Anyway if I recall correctly, the DMI System Vendor should be GOOGLE in
Google's coreboot for Caroline too, but I'm not 100% sure and cannot check
right now.
By the way please note that this is the DMI System Vendor and not the DMI
BIOS version string, which indeed starts with "Google_" in the shipping BIOS
(but not in coreboot, see f56db262e46d3368ee4e5c9e19797853cab382cd).
