Screen blanking works just fine when I close the lid. I get the ACPI event and then call xset to (un)blank the screen from a script. I'd be happy to make my kernel (somewhat patched version of Linux 2.4.21-rc1-ac3 with ACPI patches) and X binaries (Debian unstable, XFree 4.2.1.1) available to anybody who wants to investigate this problem further.
