Hapless Hero's nice summary confirms the things I have observed and includes others besides (such as the fact that the problem also occurs with 32-bit versions of the OS). I have only two things to add:
- I have two 64-bit linux systems. The 100.14.19 driver fails as described on the system with an AMD Athlon(tm) 64 X2 Dual Core Processor 4400+ and GeForce 7300 GS graphics card, but it works fine on a dual core dual processor Intel(R) Xeon(TM) CPU 3.20GHz system with a Quadro NVS 285 graphics card.
- The legacy driver 96.43.01 works fine with the AMD system.
So yes, it seems to be a combination of linux, dual-core processors, and the 100.14-series of drivers. It may also be related to the ASUS mother board. (My AMD system has an ASUS A8N-E Mainboard; the Intel system is from Dell.)
