This is what I originally suspected. However, I believe Rosimildo and Erik
have both successfully run cdtest.exe using interrupt-driven console I/O.
Hence my confusion...
Is this true, Erik, Rosimildo?
I haven't looked closely before, so how does one turn on polling for
general I/O in the x86 BSP's?
Joel, why don't we just change the printf's in cdtest.exe to printk's and
not worry about this any more?
Another place where polling I/O is required is for the various timing
tests. Would using printk in these cases be alright?
