Рискнул все же поставить свежесобранное ядро 2.4.21rel и перегрузить
машину по ssh... и ядро завелось, ура! Теперь все выглядит гораздо
приличнее, IDE контроллер на ICH5 распознался, диски нормально
отконфигурировались на UDMA(100). Но есть и непонятки: собирал ядро с
HIGHMEM (установлен 1 гигабайт), поддержкой LOCAL APIC и IO-APIC, но без
поддержки ACPI (вроде бы :). При загрузке ядро явно изображает из себя
smp вместо up и даже находит 2 процессора 8-[]. Второй потом правда
исчезает как-то незаметно. Это нормально? Ну и еще подозрительные места
в dmesg есть:

Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 941M
agpgart: Unsupported Intel chipset (device id: 2578), you might want to try agp_
try_unsupported=1.
agpgart: no supported devices found.

 ... (выглядит уже не так страшно как раньше, но что с этим делать?
      agp_try_unsupported=1 - это параметр ядра?)
