Yes, I checked that:
CONFIG_IP_PNP=y this should be the kernel-autoconfig
CONFIG_IP_PNP_ENABLE=y
CONFIG_IP_PNP_DHCP=y
CONFIG_IP_PNP_BOOTP=y
CONFIG_IP_PNP_RARP=y
[...]
CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
CONFIG_ROOT_NFS=y this is the root-NFS part
CONFIG_NFSD=y
CONFIG_NFSD_V3=y

Yep. It is, IIRC, an old ISA card. I musr assume that 2.4.* does support
them as the options are still there.
CONFIG_NET_ETHERNET=y
CONFIG_RTL8139TOO=y this is I still need to install (100mbps)
CONFIG_8139TOO_8129=y
CONFIG_NET_ISA=y
CONFIG_NE2000=y this one is installed, and works for 2.2.*
CONFIG_NET_EISA=y
CONFIG_EEXPRESS_PRO100=y these two are used in other boxen here
CONFIG_NE2K_PCI=y
Those 8129/8139 variants shouldn't trample on each other, should they?

Something like that. Retyping from the screen next to me:
All well until including to
hda: ...
hdb: ...
Uniform CD-ROM driver Rev....
Partition check:
hda:
and the trouble starts on that last line with

Yes. The 2.4.* ones that fail are around 820 to 840kb, the 2.2.* ones that
work are around 620 to 695kb, depending on what other (unused) stuff I left
enabled.
