sticore: don't activate unsupported GSC STI cards on HPPA

On HPPA there exists some older GSC graphics cards, which need special
graphic-card-BIOS patching to become supported.  Since we don't have yet
implemented the patching, it's better to detect such cards in advance,
inform to the user that there are known problems and to not activate the
card.

Problematic GSC cards and BIOS versions are:
* Hyperdrive/Hyperbowl (A4071A) graphics card series:
   * ID = 0x2BCB015A (Version 8.04/8)
   * ID = 0x2BCB015A (Version 8.04/11)
* Thunder 1 VISUALIZE 48 card:
   * ID = 0x2F23E5FC (Version 8.05/9)
* Thunder 2 VISUALIZE 48 XP card:
   * ID = 0x2F8D570E (Version 8.05/12)
* Some Hyperion and ThunderHawk GSC cards
