IIRC, a C++ compiler doesn't have to support inline assembly. But almost 
all C++ compilers support some way to write inline assembly.

Each compiler can have its own syntax for inlining assembly in the code; 
and each one can have its own assembly syntax; and each different 
architecture will have its own assembly syntax. So no, it won't work 
with all compilers.

Ever heard of GCC? http://gcc.gnu.org :)

Also, a useful document about assembly in GCC:
http://www.delorie.com/djgpp/doc/brennan/brennan_att_inline_djgpp.html
(this doc is a little outdated; GCC now supports both AT&T and Intel 
syntax, you just have to use the directive ".intel_syntax" or 
".att_syntax", or compile with "-masm=att" or "-masm=intel")

You mean you want to control your video hardware directly? The operating 
system is in charge of the hardware handling, you can only use the 
provided API. Inside an OS, you'll have as much control over your video 
hardware with assembly as with C++ or almost every other language. If 
you want to access the hardware directly you can't have an OS in your way.
