Unfortunately, the "ht" flag just means that the machine supports the
hyperthreading way of checking how many logical processors there are in
the machine. In this case, I believe that the absence of the "siblings"
field means that the processor doesn't actually support more than one
logical processor (effectively, it doesn't support hyperthreading).

Similarly, I think you need the "lm" flag for 64 bit mode.
I'd agree with your other suggestions. Linux should be able to make full
use of available memory without manual reconfiguration.
Hope this helps,
