I'm afraid there was my mistake. No luck in reproducing this with patched kernel.
I've updated BIOS (305 -> 307, ASUS F3Jc) - unpatched kernel (rc8, rc7) oopses.
Made some changes to acpi_ex_system_memory_space_handler:
static int prev_ebx = 0;
struct pt_regs *regs = task_pt_regs(current);
[..]
if (prev_ebx != regs->bx) {
printk("EAX: %08lx EBX: %08lx ECX: %08lx EDX: %08lx\n",
regs->ax, regs->bx, regs->cx, regs->dx);
prev_ebx = regs->bx;
}
Kernel oopses at acpi_ex_system_memory_space_handler+0x75, which is
mov 0x8(%ebx),%edx /* 0x8(%ebx) == mem_info->mapped_physical_address */

I also have changed show_registers(struct pt_regs *regs) to __show_regs(regs, 0); after the stack trace.
Here are 2 oopses (they are similar):
Kacpid not tainted
