Kernel panic. Someone can read/understand this log?

Question

Hi:
I have experienced 3 systems panics during last 3 months, after some upgrading: ATI X800 board and a second display. This happened the three times while the machine was iddle, I mean left my desk for 1 hour or so and when I come back I found the fans blowing full power. Never had any problem while working (video editing and graphic design).
I hope someone can read this error message and give me some directions about where could be the reason:
panic(cpu 1 caller 0x0028C234): mget MCHECK: m_type=3611 m=520ece00
