It can be enabled by putting "bios_patching true" in the VESA settings
file.
This patching does not work yet on modern hardware, but the detection
code to decide if we should try patching still says it found the
modetables. In this situation we can crash the BIOS or other weird
things can happen.
To avoid these problems, and because VESA is supposed to be the failsafe
option, disable this code by default, and let people who want to
experiment with it first enable it in the settings file.
Should fix#17633.

Since not everyone likes the default, make it an option in the vesa
settings file. Note setting a mode with the Screen prefs overwrites
the file so it will discard the option.
Also move the code to get_mode_from_settings() since we can't load driver
settings as early as vesa_init().

kernel settings file. As pointed out by Rene, there's otherwise no way to
enable ACPI when the settings file is absent, as there's only a disable switch
in the boot menu.
* Remove MADT dumping as it isn't really implemented. This info can actually be
printed in the IO-APIC code now.

causes the memory beyond 4 GB to be ignored.

While there has been no reports of fan or temperature problems that we know of,
there are rumours that this might happen.
It's a good idea to check that fans and temperature works as normal
just to be safe.

This saves ~0.5s of boot time here, but I suspect it might be better for CD.
Enabled loadSymbols in kernel settings so the behavior should be the same as before this change.

* oshaiku.c is based on a different original from a stub, therefore it
looks like a lot of comment changes.
* achaiku.h is redone completely.
* dpc is added as boot module.
* acpi_busman.c now does all mandatory steps to init.
* style fixes
* added another acpi kernel settings to avoid full init for debugging.

patch from about a year ago (I couldn't use any code of his yet, though,
but there are a few things left). The emergency keys are triggered by
pressing Alt-SysReq + key.
* By default, only Alt-SysReq+'d' is used as a means to deliberately enter
the kernel debugger. F12 belongs to userland again, now :-)
* Debugger add-ons now have another optional method to implement their own
emergency keys - 'd' for the debugger cannot be overridden, though.
* The mechanism can be turned off via a new kernel setting, so it's not that
easy anymore to "crash" Haiku if you don't want to.
* Right now, the PS/2 driver, and the pre-input_server in-kernel debugger
keyboard mini-driver support this, USB not yet.
* Minor cleanup.

to get the non-default setting. Explained default setting in comments.
