Kernel 386 installed instead of 686

It is just my opinion, but I feel that the lack of stable binary
interface between kernels is a HUGE limitation on the viability of linux
for widespread uptake. MOST users are completely incapable of
recompiling modules for their specific kernel, thus it is necessary for
everything to be precompiled. That leaves either a standardized binary
interface to kernels of different builds, or a standardized kernel for
each generation of a product as the only options.
Just look at what corporate america and pc support companies do, they
provide identical hardware, identical software, and then they support
it. It makes compatibility testing possible, and comprehensive support
of not so knowledgeable users a possibility. Having near infinite
variations in configuration is fun and good for a person like myself who
customizes everything, but if I am working on a friends machine, or on a
lab of machines, I want standardization.
Even the number of kernels available in Ubuntu starts becoming
rediculous 386/686/686smp/k7/k7smp. Ubuntu does a good job of providing
everything for all flavors, but if you start playing with more exotic
hardware you find more and more things that are compiled for only the
386 kernel with no facilities for recompiling. This doesnt help me when
Just my 2 cents.
