If I close the lid I receive this error

ACPI breakpoint: Executed AML Breakpoint opcode

I think that the problem is the i810 driver. I thought it was a memory
allocation problem so I tried to reserve the memory in xorg.conf with
the option VideoRam 32768 (and also tried up to 128Mb ... I have 1Gb
ram) but it did not work. 

I posted the same message on the linux on Thinkpad mailing list and I
received this answer

I had already tried (a) but abandoned since the Inter driver works only
on 2.4.* kernels. I will try (b) since they provide demo drivers. In the
meanwhile I discovered this, 
http://sourceforge.net/projects/i855crt
which may be worth trying (but I need a monitor or a videobeamer to test
my external monitor exit and I do not have one here at home)

Thanks for your help.
