UP Boot on hang in 2.1.90-pre2 and 2.1.90-pre3

I have an otherwise very stable machine which hangs midway through the boot
process on the last two prepatches. The last thing it prints is the Serial
driver and ttyS00/01 announcements. I do have parallel printer and APM
support turned on in these kernels, though there is no problem in 2.1.89 or
2.1.90-pre1.

Kernel is compiled with gcc 2.7.2.3 under Red Hat 5.0 with SMP not set and
CFLAGS_NSR not used (as for the working 2.1.86, 2.1.88, 2.1.89, 2.1.90-pre1
and many previous kernels). I compiled the 2.1.90-pre2/3 kernels at least
3 separate times with slightly different configurations, all with the same
result.

>From the 2.1.89 boot sequence, with the same configuration as the pre3
failure:
...
Starting kswapd v 1.5
Serial driver version 4.24 with no serial options enabled
ttyS00 at 0x03f8 (irq = 4) is a 16550A
ttyS01 at 0x02f8 (irq = 3) is a 16550A
**** This is as far as it gets in 2.1.90-pre[23] ****
lp: driver loaded but no devices found
APM BIOS version 1.2 Flags 0x03 (Driver version 1.4)
Entry f000:6a1c cseg16 f000 dseg fd4f cseg len e6ff, cseg16 len 0, dseg

Connection version 1.2
AC on line, battery status unknown, battery life unknown
battery flag 0x80, battery life unknown
Real Time Clock Driver v1.09
Non-volatile memory driver v1.0
Sound...

The system is a Pentium 166/83 with 32 MB EDO RAM and a 430HX chipset on a
1-year-old ASUS motherboard. It has an ESS1688 ISA PnP sound card, SVEC
21140 and PCI NE2000 clone Ethernet, and an STB S3 ViRGE video card. Yes,
it's a bit overclocked, but it runs cool and its stability is extremely
well tested under many different kernels.

Were there any changes to APM or parallel port stuff between the pre1 and
pre2 patches, or weird compiler directives or CPU initialization? And is
anyone else seeing UP hangs of this kernel? If not I'll try to pin this
down a bit further.
