No.

Yes. Well, no... I don't see that option in my .config. I did specify the amd64 bit archictecture, but I don't know what that means in .config terms. Here's what's set under "# Processor type and features":
CONFIG_X86_PC=y CONFIG_MK8=y CONFIG_X86_CMPXCHG=y CONFIG_X86_XADD=y CONFIG_X86_L1_CACHE_SHIFT=6 CONFIG_RWSEM_XCHGADD_ALGORITHM=y CONFIG_X86_WP_WORKS_OK=y CONFIG_X86_INVLPG=y CONFIG_X86_BSWAP=y CONFIG_X86_POPAD_OK=y CONFIG_X86_GOOD_APIC=y CONFIG_X86_INTEL_USERCOPY=y CONFIG_X86_USE_PPRO_CHECKSUM=y CONFIG_HPET_TIMER=y CONFIG_HPET_EMULATE_RTC=y CONFIG_SMP=y CONFIG_NR_CPUS=2 CONFIG_PREEMPT=y CONFIG_X86_LOCAL_APIC=y CONFIG_X86_IO_APIC=y CONFIG_X86_TSC=y CONFIG_X86_MCE=y CONFIG_X86_MSR=y CONFIG_X86_CPUID=y CONFIG_NOHIGHMEM=y CONFIG_MTRR=y CONFIG_HAVE_DEC_LOCK=y

Ok, I guess I'll try that (tomorrow, unless I hear any better suggestions before then).
[I thought highmem was something completely different -- that it declared a watermark and memory above that watermark was treated differently. However, I guess I understand that this might have the side effect of bumping things around such that I get access to the memory.]
