Odpoviem si teda sam: riesenie problemu je pomerne jednoduche. Pri boote
noveho jadra (k zmene doslo niekde medzi 2.6.6 a 2.6.8) treba pouzit
parametre "hda=stroke hdc=stroke".

V starsich jadrach (< 2.6.7) bolo potrebne mat zapnutu spominanu volbu
CONFIG_IDEDISK_STROKE. V novsich jadrach to treba jadru povedat
parametrom pri bootovani.

Odpoved sa nachadzala v linux-2.6.8/drivers/ide/ide-disk.c vo funkcii
idedisk_check_hpa():

-------------------------------%<-------------------------------
static inline void idedisk_check_hpa(ide_drive_t *drive)
{   
    unsigned long long capacity, set_max;
    int lba48 = idedisk_supports_lba48(drive->id);

    capacity = drive->capacity64;
    if (lba48)
        set_max = idedisk_read_native_max_address_ext(drive);
    else
        set_max = idedisk_read_native_max_address(drive);

    if (set_max <= capacity)
        return;

    printk(KERN_INFO "%s: Host Protected Area detected.\n"
             "\tcurrent capacity is %llu sectors (%llu MB)\n"
             "\tnative  capacity is %llu sectors (%llu MB)\n",
             drive->name,
             capacity, sectors_to_MB(capacity),
             set_max, sectors_to_MB(set_max));

    // nasledovne 2 riadky pribudli v 2.6.8 a nahradil sa tym
    // podmieneny preklad v starsich jadrach (CONFIG_IDEDISK_STROKE)
    if (!drive->stroke)
        return;

    if (lba48)
        set_max = idedisk_set_max_address_ext(drive, set_max);
    else
        set_max = idedisk_set_max_address(drive, set_max);
    if (set_max) {
        drive->capacity64 = set_max;
        printk(KERN_INFO "%s: Host Protected Area disabled.\n",
                 drive->name);
    }
}

Jednoduchsiu odpoved mozno najst v linux-2.6.8/Documentation/ide.txt:

---------------------------------------%<---------------------------------------
 "hdx=stroke"           : Should you have a system w/ an AWARD Bios and your
                          drives are larger than 32GB and it will not boot,
                          one is required to perform a few OEM operations first.
                          The option is called "stroke" because it allows one
                          to "soft clip" the drive to work around a barrier
                          limit.

Dakujem sam sebe za vyriesenie problemu. ;-)
