Sadly, NO.

I did it first with the standard CFLAGS, then with mine, which I used for 
several years on my Athlon systems (the later running fine with 2.5.45 as 
always). All were full rebuilds. Then I've tried it with and without "HugeTLB 
file system support".

New stuff is at the beginning of the .config file:

#
# Automatically generated make config: don't edit
#
CONFIG_X86=y
CONFIG_MMU=y
CONFIG_SWAP=y
CONFIG_UID16=y
CONFIG_GENERIC_ISA_DMA=y

Here comes a diff of my running 2.5.45 .config file and the one for 2.5.46:

src/linux> diff ../linux-2.5.45/.config .config
4a5,6

Even without HUGETLBFS and EXT2_FS_XATTR it will not run.
