Well, you'd better tell me about them .. as far as I know there are
none such :). (I have a 64 bit AMD machine). Here's the build as it goes
on amd64 (I typed "make" in the 2.4.33 src dir).

Are you sure you have configured and built your kernel? The kernel
.config file should start out like:

# Automatically generated make config: don't edit
# Linux kernel version: 2.6.15.5
# Tue Mar 14 19:12:43 2006
#
CONFIG_X86_64=y
CONFIG_64BIT=y
CONFIG_X86=y
CONFIG_SEMAPHORE_SLEEPERS=y
CONFIG_MMU=y
CONFIG_RWSEM_GENERIC_SPINLOCK=y
CONFIG_GENERIC_CALIBRATE_DELAY=y
CONFIG_X86_CMPXCHG=y
CONFIG_EARLY_PRINTK=y
CONFIG_GENERIC_ISA_DMA=y
CONFIG_GENERIC_IOMAP=y
CONFIG_ARCH_MAY_HAVE_PC_FDC=y


And here's the promised build log
