Ken Sharp, thank you for reporting this bug to Ubuntu. linux-lts-saucy reached EOL on August 2014.
See the following documents for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases
https://wiki.ubuntu.com/Kernel/LTSEnablementStack

However, while your statement on how your graphics card is not supported by the proprietary nvidia drivers in linux-lts-trusty was noticed, I'm not seeing evidence to this. As per nvidia's website, the latest version of the driver available for your card is 173.14.39. Also, this is available in both Precise with linux-lts-trusty and in Trusty itself as per https://launchpad.net/ubuntu/+source/nvidia-graphics-drivers-173 . Hence, it would appear it is in fact supported, but wasn't working when you last tested it. I would recommend filing a bug report on the graphics card issue via:
ubuntu-bug xorg

Please ensure you have the package xdiagnose installed, and that you
click the Yes button for attaching additional debugging information.

Pivoting back to the scope of this report, would you be able to either
downgrade your kernel to 3.2.x to maintain supportability and security
updates, or upgrade to linux-lts-trusty+ so troubleshooting may continue
on a supported release?

As well, you may have already done this, but it wouldn't hurt to rule
out a hardware issue by stress testing the CPU via
https://help.ubuntu.com/community/Checkbox .

Title:
  Hyperthreading not always detected

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  From a cold boot (power off --> power on), this system doesn't always
  detect the presence of Hyperthreading on the processor. Note: warm
  reboot has very different problems so cannot be tested.

  It *usually* does, but on occasion for no obvious reason the system
  reports a single CPU (HT systems report two CPUs to increase
  performance).

  Despite all the articles claiming the opposite; this noticeably
  reduces performance of the system, especially in multi-threaded
  applications such as Google Chrome (in the case of Chrome the
  difference in response is considerable!)

  linux-lts-trusty is NOT an option as it is incompatible with my
  graphics drivers (no longer supported).
