I checked the distribution I'm using (debian) and the kernel shipped with it 
does not have  CONFIG_X86_GENERIC set.  This means _when_ they ship a 2.6.27 
kernel it won't work with Virtual PC so I won't be able to even install it.
However, with Linus's patch I am guaranteed to work for all kernels built for 
X86_32 and even for X86_64 because in that case the virtual environment will 
support the multibyte NOPs.  I need Linus's fix in order to support the 
Linux-using virtual pc community.  I don't have the resources to lobby each 
individual distribution about their kernel config.  I want it to just work.
